A marching method for calculating viscous gas flows in ducts
Abstract
A marching algorithm for calculating supersonic viscous gas flows in ducts is proposed which is characterized by high stability and accuracy. The results obtained using this method are compared with exact solutions and results obtained by an approximate method based on simplified Navier-Stokes equations. It is shown that the marching procedure proposed here can be successfully used for calculating flows in ducts of complex configurations.
