Notes on the unsteady rectilinear motion of a perfect gas. Part 5: A nonuniformly traveling shock wave in an LMS gas
Abstract
A relatively simple flow of an LMS gas is considered. The LMS gas is nonhomentropic, but the entropy distribution is chosen in such a way that generalized Riemann invariants r* and s* exist. It is shown that a flow is possible, consisting of two domains, each with r* and s* constant, while the separation between the domains is a normal shock wave that satisfies the RankineHugoniot conditions. The shock wave travels with a variable velocity. Exact solutions of such cases are rare.
