Abstract : The specific nature of the blast wave problem as a boundary (initial) value problem with moving boundaries in the theory of a system of quasi-linear partial differential equations gave the impetus for developing an approach which is based on geometric-analytical grounds. The idea is to make maximum use of the geometric configuration of the shock wave itself by employing a so-called 'natural system of coordinates'. This makes it possible to handle the shock transition conditions in a relatively simple manner. Furthermore, the boundary value problem with moving boundaries is reduced to a problem with fixed boundaries in a space-time continuum. As a consequence, the blast wave problem can be treated as an initial value problem in the classical sense. (Author)
