Kuropatenko, V. F.; Shestakovskaya, E. S.; Yakimova, M. N. Shock waves in gas sphere. (Russian. English summary) Zbl 1338.76110 Vestn. Yuzhno-Ural. Gos. Univ., Ser. Mat. Model. Program. 9, No. 1, 5-19 (2016). Summary: Mathematical modelling is widely applied for researches in all natural sciences, industries, economy, biology and other areas. Already existing or new created models and numerical methods are used for the solution of specific problems. The most reliable way to check the adequacy of the differential scheme is to compare the numerical solution with the precise solution of the problem where it is possible. As an example of such “reference” solution we construct a precise solution for the problem of a convergent shock wave and dynamic gas compression in a spherical vessel with an impermeable wall. Initially, the external border of the gas begins to move stepwise with a negative velocity, and the shock wave begins to propagate from border to gas. Acceleration of the border and sphericity determine the motion of the shock wave and the structure of the gas flow between the shock front and border. The considered problem formulation is fundamentally different from previously known statements of the problem of self-similar shock wave convergence to the center of symmetry and its reflection from the center with no boundary of gas.
