Abstract

The LU-ADI factorization algorithm for the Navier-Stokes computations has been developed by using the diagonally dominant LU factorization. The space variable time stepping technique is also implemented to the code. A new dissipation model using a flux limiter coupled with a central difference scheme is proposed and successfully applied to prevent spikes at the shock wave. Effects of grid distributions are investigated to evaluate the reliability of Navier-Stokes solutions. A new algebraic grid generation technique was used for the grid systems of the present computations.
