Abstract

A computational technique is described to solve Reynolds averaged Navier-Stokes (RANS) equations. Procedures are presented to obtain faster steady-state solution of the RANN. Numerical aerodynamic simulation results are presented as well as analysis results for parameters of a transonic cascade. A possibility is demonstrated to change flow structure and to improve aerodynamic characteristics of the transonic cascade.
