Application of steger-warming flux vector splitting (FVS)‎ method to nozzle flow modeling

Abstract EN

The Steger-Warming flux vector splitting is used for the solution of two-dimensional Euler equations.

An implicit finite difference scheme is used.

A computer code is developed and tested for subsonic, transonic, and supersonic flow regimes.

The method is then applied to the flow through a convergent-divergent nozzle and a divergent nozzle, both with strong shocks.

Further factorization has been done to the formulated finite difference equations.

As a result of the new factorization, the CPU time to reach the steady state solution decreased significantly to about 65% without altering the accuracy.

Comprehensive comparisons with the MacCormack method are presented.
