Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

A finite-difference method is proposed for solving the inverse problem of the turbulent boundary layer of an incompressible fluid as applied to the calculation of geometric and aerodynamic characteristics for preseparation diffusers. The effect on these characteristics of the length of the transition area from a constant cross section channel to a preseparation diffuser is investigated. The reliability of the results of the calculation is confirmed by their satisfactory agreement with experimental data of various authors.
