ABSTRACT
It is illuminating to study attempts at the exact solution of one-dimensional gasdynamic equations, which would throw light on the structure of the solutions, the blast waves being one class of solutions of these equations. In the present section we consider the work in this context by McVittie (1953) and in the following section that by Keller (1956). The former is in Eulerian co-ordinates while the latter uses Lagrangian co-ordinates (cf. Taylor (1950) and Von Neumann (1941) for the blast wave problem).
