Numerical simulation of separated transonic flow about the boat-tailed objects

The properties of the separated flows around boat-tailed objects, especially in transonic regimes, are very complex and understood to date not very well. With variation of free-stream Mach number the flow structure: the size and location of separation areas, internal supersonic regions, the position and intensity of internal shocks - varies significantly. These flow properties determine the complexity of the numerical modeling problem and high demands on the algorithms used. The paper presents a comparison of numerical results obtained on the basis of different mathematical models with experimental data. The investigation of fundamental properties of transonic flow transformation are presented also.
