A High-Order Finite Element Method for the Linearised Euler Equations

Sound propagation in complex non-uniform mean flows is an important feature of turbofan exhaust noise radiation. The Linearised Euler Equations are able to represent the strong shear layer refraction effects on the sound field, as well as multiple length scales. Frequency domain solvers are suitable for tonal noise and considered a way to avoid linear instabilities, which may occur with time do...

A High Order Finite Dierence Method for Random Parabolic Partial Dierential Equations

In this paper, for the numerical approximation of random partial differential equations (RPDEs) of parabolic type, an explicit higher order finite difference scheme is constructed. In continuation the main properties of deterministic difference schemes, i.e. consistency, stability and convergency are developed for the random cases. It is shown that the proposed random difference scheme has thes...

High-Order Accurate Discontinuous Finite Element Solution of the 2D Euler Equations

This paper deals with a high-order accurate discontinuous finite element method for the numerical solution of the Euler equations. The method combines two key ideas which are at the basis of the finite volume and of the finite element method, the physics of wave propagation being accounted for by means of Riemann problems and accuracy being obtained by means of high-order polynomial approximati...

High Order Finite Element Discretization of the Compressible Euler and Navier-Stokes Equations

We present a high order accurate streamline-upwind/Petrov-Galerkin (SUPG) algorithm for the solution of the compressible Euler and Navier-Stokes equations. The ow equations are written in terms of entropy variables which result in symmetric ux Jacobian matrices and a dimensionally consistent Finite Element discretization. We show that solutions derived from quadratic element approximation are o...

Euler Equations Flow Field Dependent Finite Element Method

The Flow Field Dependent Variation Method (FDV) uses built in parameters that arise from its formulation to control seamless transition from one flow regime to another. This method was originally developed by Dr T.J. Chung at the University of Alabama in Huntsville. This method does not require any added artificial viscosity and used local flow conditions to control the accuracy and stability o...
