Numerical Simulation of Unsteady Flow in a Compressor Rotor Cascade

摘要

Unsteady flow in a two-dimensional compressor rotor is computed by solving the time-dependent compressible Navier-Stokes equations for flow between two adjacent rotor blades. The computations are carried out on a CDC Cyber 845 computer and a CRAY XMP computer using MacCormack's explicit finite difference scheme. The primary objective of this program is to numerically simulate the rotor flow accounting for the effects of wakes from the upstream stator and inlet guide vane. Particular attention is focused on the influence of unsteady effects on the mass flow rate, shock structure, and shock wave-boundary layer interaction.
