Abstract

The 3D turbulent supersonic flow over a body of revolution at various angles of attack alpha is studied numerically and experimentally. The body surface incorporates a forward-facing step near its midpart and a nose cone. Experiments were conducted in a wind tunnel of the Research Institute of Mechanics, Moscow State University, at the Mach number of 3 for various lengths L of the distance between the step and nose cone. Numerical simulations were performed with a finite-volume solver ANSYS CFX-15. The study reveals bands of alpha and L in which the pressure on the leeward side of step abruptly increases and exceeds the pressure on the windward side.
