ABSTRACT

The dependence of pressure and heat flux perturbations towards the cylinder on the period of spatial perturbations of different types and different forms of supersonic flow at various Reynolds numbers, Mach numbers, and temperature factors has been studied on the basis of the numerical solution of the Navier-Stokes equations with application of high-resolution grids for the shock wave front
