Computation of gas-dynamic parameters and heat transfer in supersonic turbulent separated flows near backward-facing steps (Q2746941)

Computation results of plane turbulent flows in the vicinity of backward-facing steps with leeward-face angles \(\beta = 8, 25\), and \(45^\circ\) for Mach numbers \(M_\infty = 3\) and 4 are presented. The averaged Navier-Stokes equations supplemented by the Wilcox model of turbulence are used as a mathematical model. The boundary layer equations were also used for the case of an attached flow \((\beta = 8^\circ)\). The computed and experimental distributions of surface pressure and skin friction, the velocity and pressure fields, and the heat transfer coefficients are compared.
