The accuracy and efficiency of several lower and higher order time integration schemes are investigated for engineering solution of the discretized unsteady compressible Navier-Stokes equations. Fully implicit methods tested are either the backward differentiation formulas (BDF) or stage-order two,

A technique is described for solving the compressible flow equations in subsonic flow. The general quasi-linear equation V . g V v = 0 is considered with g a function of V v . V v , and iterations of the form V . g , V U , + ~ = 0 are analysed, where go is suitably chosen and g , defined from u, for
A method capable of solving very fast and robust complex non-linear systems of equations is presented. The block adaptive multigrid @AM) method combines mesh adaptive techniques w i t h multigrid and domain decomposition methods. The overall method is based on the FAS multigrid, but instead of using
## Abstract A numerical scheme is developed to study the stability of the linearized vorticity equations. The linear growth rates of KelvinβHelmholtz instabilities resulting from a velocity shear are calculated numerically. The theory of neutrally stable waves, in two dimensions, is extended to inc
