Abstract

This paper presents the results of numerical simulation of turbulent flows in plane symmetric diffuser. Investigates the influence of an opening angle of the diffuser on the aerodynamic characteristics. Also examines the impact of passive methods of control of the boundary layer as the separation walls and the control vanes on the aerodynamic characteristics of the diffuser. The aim of present investigation is modeling with the help of methods of numerical gas dynamic flow at diffuser with different opening angle, numbers М≤0,5 and following comparing numerical calculation and experimental data.
