Numerical and experimental study of a supersonic flow around a cylinder with gas-permeable porous inserts at an angle of attack.

The paper presents the results of numerical and experimental modeling of a supersonic (M∞ = 7) flow around a cylinder with a front gas-permeable porous insert at different angles of attack. A three-dimensional skeletal ring model of a highly porous cellular material has been constructed and implemented for the numerical simulation of the problem. Experimental studies were carried out in a T-327 wind tunnel of the ITAM SB RAS. The calculated data of the aerodynamic drag coefficients are compared with the results of experiments.
