Separated Flow Problems within the Transonic and Supersonic Flow Regimes.

Abstract

The base pressure associated with supersonic axisymmetric flow past a backward facing step employing previously developed analysis of recompression, reattachment, and redevelopment processes, has been calculated for small supersonic approching flow Mach numbers with thin initial boundary layers. The model of dealing with transonic flow past a backward facing step in two-dimensional or axisymmetric configuration has been successfully developed. Large scaled calculations of the turbulent Navier-Stokes equation based on the 'two-equation model' has been carried out for the low speed flow past a two-dimensional backstep where a considerable amount of hot-wire data is available for compression and good description of the overall flow pattern has been obtained. Numerical calculations of the potential flow after hodograph transformation have been proved to be fruitful by solving many previously unsolved problems where the effect of gravitation predominates.
