Spherical, Cylindrical and One-Dimensional Flows of Compressible Fluids

Excerpt from Spherical, Cylindrical and One-Dimensional Flows of Compressible FluidsRelatively few boundary value problems involving spherical or cylindrical flows of compressible fluids have been solved exactly. In order to solve more problems of this type, particularly those involving variable entropy, we have investigated the flow differential equations, at first without regard to initial or boundary conditions. In this way a class of non-isentropic solutions of the differential equations, depending upon an arbitrary function, has been obtained. Then, in the second phase of the investigation, the arbitrary function is adjusted to satisfy particular initial or boundary conditions. In this way the free expansion of a sphere of gas into a vacuum has been treated, as well as the propagation of finite and strong shocks in variable media. The latter treatment includes Primakoff's point-blast solution as a special case.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
