Calculation of two non-stationary diffraction problems by an explicit algorithm with the second order of accuracy
Two non-stationary diffraction problems are studied numerically, i.e. non-stationary transition from regular Mach reflection on a concave and convex cylinder and the departure of a plane shock wave to a submerged chamber and transverse supersonic flow. The results are compared to those of [1-7]. The calculations were carried out by an explicit TVD-scheme [8] of the 2-nd order of accuracy with respect to time and space for the Euler equations. 2D and 3D curvilinear grids were employed constructed making use of the method based on the solution of the vector Poisson equation [9] with the right-hand sides being ñontrol functions.
