Numerical Simulation of Compressible Navier-Stokes Flow in a Double Throat Nozzle

摘要

Flow through a double throat nozzle has been computed for Reynolds numbers by 100, 400 and 1,600 on three different grid sizes. The computations were performed using a modified two-dimensional version of Shang's Navier Stokes code which employs MacCormak's explicit finite difference algorithm. The computations establish a benchmark against which new developments can be verified and also add to the growing confidence in this approach for applications to more complex flow situations.
