Development of a Design-Oriented Navier-Stokes Cascade Analysis

Abstract

Under a Phase I SBIR effort, an existing Navier-Stokes cascade computer code has been automated and recoded to form a design oriented cascade calculation procedure. The procedure consists of two distinct codes which are (1) the coordinate generation code and (2) the Navier-Stokes solver. With the revised procedure, the coordinate generator allows a new user to obtain coordinate systems with a minimum of input data. The Navier-Stokes procedure has been recoded to minimize required input and to decrease run time per time step. In addition, a run protocol has been developed to obtain rapid convergence. A demonstration calculation has been run which yields a converged solution in less than 300 CPU secs of unvectorized CRAY-1 run time.
