摘要

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 freestream Mach numbers is Min = 2–4.5.
