Gradient-Augmented Level Set Method and Jet Schemes

###### (with B. Seibold and R.R. Rosales)

The level set approach represents surfaces implicitly, and advects
them by evolving a level set function, which is numerically defined on an Eulerian grid.
Here we present an approach that augments the level set function values
by gradient information, and evolves both quantities in a fully coupled fashion.
This maintains the coherence between function values and derivatives, while exploiting
the extra information carried by the derivatives. The method is of comparable quality to
WENO schemes, but with optimally local stencils (performing updates in time by using information
from only a single adjacent grid cell). In addition, structures smaller than the grid size can be
located and tracked, and the extra derivative information can be employed to obtain simple and accurate approximations
to the curvature. We analyze the accuracy and the stability of the new scheme, and perform benchmark tests.

Jet-Schemes are extensions of the GALS Method where higher order derivatives are used to construct the Hermite interpolation. Consequently, higher-order time stepping must used so that the overall (global convergence) order of the scheme is improved. We constructed Jet-Schemes of global order up to 5 in 2D and 3D successfully. The following papers contain details and a comparison of Jet-Schemes with WENO and DG.

Advection of Arbitrary Sets: Characteristic Mapping Method

###### (with O. Mercier)

In this paper, we present a new numerical method for advecting
arbitrary sets in a vector field. The method computes a transformation
of the domain instead of dealing with particular sets. We propose a way of
decoupling the advection and representation steps of the computations, resulting
in significant reductions in computational times over other methods while still
guaranteeing accuracy. The decoupling also allows one to advect multiple sets at low
computational cost, and makes the method highly parallelizable. Results are presented
in two and three dimensions, and accuracy and efficiency are studied.

Adaptive Gradient-Augmented Level Set Method with Multi-Resolution Error Estimation

###### (with D. Kolomenskyi and K. Schneider)

A space-time adaptive scheme is presented for solving advection equations
in two space dimensions. The gradient-augmented level set method using a semi-Lagrangian
formulation with backward time integration is coupled with a point value multiresolution
analysis using Hermite interpolation. Thus locally refined dyadic spatial grids are introduced
which are efficiently implemented with dynamic quad-tree data structures. For adaptive
time integration, an embedded Runge-Kutta method is employed. The precision of the new
fully adaptive method is analysed and speed up of CPU time and memory compression with
respect to the uniform grid discretization are reported.

Poisson's Equation with Interface Jumps

###### (with A.N. Marques and R.R. Rosales)

This project has two parts:

(1) Solving Poisson's equation with jump conditions provided on a co-dim 1 interface

(2) Solving piece-wise constant coefficient Poisson's equation with interface provided on a co-dim 1 interface

In the constant coefficient case (1), we developped a technique, the Correction Function Method (CFM) which provides a correction to the RHS of the equation so that the jumps are accurately enforced. This correction is the solution to a local PDE problem (which is fast and easy to solve). Since one may compute the correction to any order of accuracy, and provided the discretization of the Laplacian is of matching order, the method is "in principle" of arbitrary order. We have constructed order 2 and order 4 schemes in 2D successfully. This is detailed in our paper.

The piece-wise constant coefficient case (2) is significantly more complicated. However, we were able to reduce it to the solving 2 CFM problems and one boundary integral (for the potential). This decomposition is close to that of described by Mayo ("The fast solution of Poisson's and the biharmonic equations on irreular regions", SIAM J. NA, 1984). Using the same ideas, we also solve Poisson's equation with arbitrary boundary conditions on an immersed boundary.

We present 2D examples of the algorithm applied to problems involving boundary conditions over complex geometries (with 4th order accuracy), and to a Poisson equation with interfaces across which the solution is discontinuous (with 3rd order accuracy).

Sharp-Interface Active Penalty Method

###### (with D. Shirokoff)

The volume penalty method provides a simple, efficient approach
for solving the incompressible Navier-Stokes equations in domains with
boundaries or in the presence of moving objects. Despite the simplicity,
the method is typically limited to first order spatial accuracy. We demonstrate
that one may achieve high order accuracy by introducing an active penalty term.
One key difference from other works is that we use a sharp, unregularized mask
function. We discuss how to construct the active penalty term, and provide numerical
examples, in dimensions one and two. We demonstrate second and third order
convergence for the heat equation, and second order convergence for the
Navier-Stokes equations. In addition, we show that modifying the penalty
term does not significantly alter the time step restriction from that
of the conventional penalty method.

An Iterative Algorithm for Computing the Measure of Generalized Voronoi Regions

###### (with L. Larsson and R. Choksi)

We present and analyze a fast algorithm for directly computing the measure of
a generalized Voronoi region associated with generators of arbitrary co-dimension. The algorithm
is based upon solving one Eikonal equation to generate a kernel-based operator whose iteration
accumulates \mass" along the closest generator. In particular, the algorithm does not require the
computation of the ridge set (Voronoi diagram) nor the gradient of the solution to the Eikonal
equation. The algorithm is shown to be .rst order and converge very quickly. Several illustrations
are presented including the computation of measures of in
uence associated with the Los Angeles
County highway system. The method can also be used for the fast computation of the centroid and
higher moments of the generalized Voronoi regions.

Global Analysis for Minimizers of Non-Convex Functionals: A Simple Approach via Convex Approximation

###### (with D. Shirokoff and R. Choksi)

We consider mass-constrained minimizers for a class of non-convex energy functionals
involving double-well potentials. Based upon a global convex lower bound to the energy, we introduce
a simple strategy to .nd su.cient conditions to infer whether a given critical point is a global
minimizer. We show that this strategy works well for the simplest of critical points, the constant
state. In doing so, we derive an almost optimal lower bound on the order-disorder curve for the
Ohta-Kawasaki energy. Focusing on the lamellar phase, we discuss how this strategy extends to
non-constant critical points.

Invariant Discretization Schemes Using Evolution-Projection Techniques

###### (with A. Bihlo)

Finite difference discretization schemes preserving a subgroup of the maximal Lie invariance group of the one-dimensional linear heat equation are determined. These invariant schemes are constructed using the invariantization procedure for non-invariant schemes of the heat equation in computational coordinates. We propose a new methodology for handling moving discretization grids which are generally indispensable for invariant numerical schemes. The idea is to use the invariant grid equation, which determines the locations of the grid point at the next time level only for a single integration step and then to project the obtained solution to the regular grid using invariant interpolation schemes. This guarantees that the scheme is invariant and allows one to work on the simpler stationary grids. The discretization errors of the invariant schemes are established and their convergence rates are estimated. Numerical tests are carried out to shed some light on the numerical properties of invariant discretization schemes using the proposed evolution-projection strategy.

Convecting Reference Frames and Invariant Numerical Models

###### (with A. Bihlo)

In the recent paper by Bernardini et al. [J. Comput. Phys. 232 (2013), 1-6] the discrepancy in the performance of finite difference and spectral models for simulations of flows with a preferential direction of propagation was studied. In a simplified investigation carried out using the viscous Burgers equation the authors attributed the poorer numerical results of finite difference models to a violation of Galilean invariance in the discretization and propose to carry out the computations in a reference frame moving with the bulk velocity of the flow. Here we further discuss this problem and relate it to known results on invariant discretization schemes. Non-invariant and invariant finite difference discretizations of Burgers equation are proposed and compared with the discretization using the remedy proposed by Bernardini et al.

**[ArXiv:1301.5955] **

By leveraging the Subgrid accuracy of the methods presented above, we can simulate the dynamics of a droplet of water impinging on a soap film.

These simulations were performed on a regular Cartesian grid and capture quantatively the various regimes found in the experiments of T. Gilet and J. Bush**[Their Paper]**.

Using a similar approach, our method can simulate the problem of partial coalescence. The subgrid accuracy of the method allows here too to compare quantatively with experiments.

Falling Liquid Films

###### (with X.D. Liu and S. Banerjee)

Liquid films are important in many industrial applications, but also from a
fundamental point of view, they are important two-phase flow systems. In this
paper, we develop a sharp interface/level set method for the Direct Numerical
Simulation (DNS) of liquid films with large interfacial deformations, and large
density ratio between the liquid and the gas phase. We use the ghost fluid
method to capture the interface motion without smoothing properties across it,
and adopt a maximization scheme for the implicit treatment of the viscous
term in the Navier–Stokes equations. Because liquid films have very low
average depth compared to the distance between waves, several innovations are
required to handle solving the equations on grid structures of high aspect ratio.
Two-dimensional (2D) calculations for wavy films falling down a vertical wall
are presented, and good agreement is found when numerical solutions are
directly compared with the experiments of Nosoko et al. [1]. Some results are
also presented for falling liquid films transitioning naturally from 2D to 3D
surface wave structures demonstrating the potential of the method for 3D fully
coupled two-phase liquid films simulations.

Concentric Fluid Shells Satability and Fiber Drawing

###### (with X. Liang, D. S. Deng, Y. Fink, S. G. Johnson)

Motivated by complex multi-fluid geometries currently being explored in fibre-device
manufacturing, we study capillary instabilities in concentric cylindrical flows of N
fluids with arbitrary viscosities, thicknesses, densities, and surface tensions in both the
Stokes regime and for the full Navier–Stokes problem. Generalizing previous work by
Tomotika (N=2), Stone and Brenner (N=3, equal viscosities) and others, we present
a full linear stability analysis of the growth modes and rates, reducing the system to
a linear generalized eigenproblem in the Stokes case. Furthermore, we demonstrate
by Plateau-style geometrical arguments that only axisymmetric instabilities need be
considered. We show that the N=3 case is already sufficient to obtain several
interesting phenomena: limiting cases of thin shells or low shell viscosity that
reduce to N=2 problems, and a system with competing breakup processes at very
different length scales. The latter is demonstrated with full three-dimensional Stokesflow
simulations. Many N > 3 cases remain to be explored, and as a first step we
discuss two illustrative N->infinity cases, an alternating-layer structure and a geometry
with a continuously varying viscosity.

Self-Sustained Nonlinear Waves in Traffic Flow

###### (with M. Flynn, A. Kasimov, B. Seibold, and R.R. Rosales)

Our research is based on the observation that the considered traffic models are similar to the equations that describe detonation waves produced by explosions. Employing the theory of denotation waves, we have developed ways to analytically predict the exact shape and the speed of propagation of jamitons. Numerical simulations of the considered traffic models show that the predicted jamiton solutions are in fact achieved, if the initial traffic density is sufficiently dense. The considered jamitons can qualitatively be found both in observed real traffic as well as in experiments. The theoretical description of the jamiton solution admits a better understanding of their behavior.
