Abstract

Results of experimental and numerical modeling of a supersonic flow around a cylinder with a frontal gas-permeable high-porosity insert aligned at different angles of attack are presented. The experiments are performed in a supersonic wind tunnel at the Mach number \(\mbox{M}_{\infty }=7\) and unit Reynolds number \(\mbox{Re}_{1}=1.5 \cdot 10^6\) m\(^{ - 1}\) in the range of the angles of attack \(0–25^\circ\). The numerical simulations are performed by means of solving three-dimensional Reynolds-averaged Navier–Stokes equations with the use of a three-dimensional ring skeleton model of the porous material. The drag and lift coefficients for a cylinder with a 95% porosity and pore diameter of 2 mm are obtained for different values of the insert length and angle of attack.
