Direct Numerical Simulation of a Supersonic Flow in the Base Region of a Circular Cylinder
A supersonic flow in the near wake behind a cylinder is considered. Pressure distributions in the base region behind a circular cylinder for various Mach numbers M∞ are obtained and analyzed by means of direct numerical simulation based on high-order approximation algorithms. For M∞ = 2.46, the results obtained in the present study are compared with available experimental and numerical data. Generation of turbulent kinetic energy is calculated for various Mach numbers.
