Numerical calculation of internal flows of a viscous gas by the use of the Navier-Stokes equations
Abstract
The Navier-Stokes equations are used to analyze viscous compressible gas flow in a plane channel of constant cross section and in a Laval nozzle at a Reynolds number of about 100. The numerical analysis employs a finite difference scheme based on the splitting of the initial equations with respect to physical processes and spatial variables. Results are presented on various types of pressure drops, including pressure drops under conditions of supersonic outlet flow.
