Algorithms for solving problems and a set of programs for mathematical modeling have been developed. The applied problems on the interaction of a pressure wave with a moving obstacle, with a moving interface of two different media, with a front of the shock wave, which the pressure wave is catching up, are solved. The use of developed mathematical models in applied problems makes it possible to determine the pressure fields that arise when other sources of physical nature act and improve electric discharge technologies.
