Abstract
The flow pattern and integral flow parameters in confusors implementing different methods of a supersonic flow compression are numerically investigated.. Model configurations are considered, consisting of a tapering inlet section and a constant cross-section, in which different types of flows take place: two-dimensional, axisymmetric or three-dimensional flow. The flow is completely turbulent and computations are based on Navier-Stokes equations and the k-ω SST turbulence model. The flow in the confusor is assumed to be supersonic everywhere, the range of free-stream Mach numbers is МH = 2 - 4.5.
