โœฆ Synopsis

Several new elements are compared to the standard trilinear velocity+onstant pressure element ( Q , -P,,)

for the solution of the three-dimensional Navier-Stokes equations by the finite element method. The test problem is the cubic wall-driven cavity with solution sought at Reynolds number of 400 and 3200. It is shown that the Q1 -P,, can be advantageously replaced by better elements and a choice among these elements is proposed.

This work presents a mixed three-dimensional finite element formulation for analyzing compressible viscous flows. The formulation is based on the primitive variables velocity, density, temperature and pressure. The goal of this work is to present a 'stable' numerical formulation, and, thus, the inte
