High-order variational Lagrangian schemes for compressible fluids

چکیده
We present high-order variational Lagrangian finite element methods for compressible fluids using a discrete energetic approach. Our spatial discretization is mass/momentum/energy conserving and entropy stable. Fully implicit time stepping used the temporal discretization, which allows much larger step size stability compared to explicit methods, especially low-Mach number flows and/or on highly distorted meshes. Ample numerical results are presented showcase good performance of our proposed scheme.

Lagrangian Averaging for Compressible Fluids
This paper extends the derivation of the Lagrangian averaged Euler (LAEα) equations to the case of barotropic compressible flows. The aim of Lagrangian averaging is to regularize the compressible Euler equations by adding dispersion instead of artificial viscosity. Along the way, the derivation of the isotropic and anisotropic LAE-α equations is simplified and clarified. The derivation in this ...
متن کاملHigh order conservative Lagrangian schemes with Lax-Wendroff type time discretization for the compressible Euler equations
In this paper, we explore the Lax-Wendroff (LW) type time discretization as an alternative procedure to the high order Runge-Kutta time discretization adopted for the high order essentially non-oscillatory (ENO) Lagrangian schemes developed in [2, 4]. The LW time discretization is based on a Taylor expansion in time, coupled with a local CauchyKowalewski procedure to utilize the partial differe...
متن کاملRecent progress on very high order schemes for compressible flows
We will talk about necessary and sufficient conditions for an entire solution $u$ of a biharmonic equation with exponential nonlinearity $e^u$ to be a radially symmetric solution. The standard tool to obtain the radial symmetry for a system of equations is the Moving-Plane-Method (MPM). In order to apply the MPM, we need to know the asymptotic expansions of $u$ and $-\Delta u$ at $\infty$. The ...
متن کاملHigh-Order Semi-Implicit Schemes for Unsteady Compressible Flow Simulations
Direct numerical simulation of stability and transition of compressible boundary layers requires high-orderaccurate and computationally ef cient numerical methods to resolve a wide range of timeand length scales associated with wave elds in the boundary layers. Explicit methods have been used mainly in such simulations to advance the compressible Navier–Stokes equations in time. However, the...
متن کاملA high-order cell-centered Lagrangian scheme for compressible fluid flows in two-dimensional cylindrical geometry
The goal of this paper is to present high-order cell-centered schemes for solving the equations of Lagrangian gas dynamics written in cylindrical geometry. A node-based discretization of the numerical fluxes is obtained through the computation of the time rate of change of the cell volume. It allows to derive finite volume numerical schemes that are compatible with the geometric conservation la...
