Excerpt from Progress Report on the Mach Reflection Calculation If X, Y are cartesian coordinates in the plane of Figure l, with the origin at the tip of the wedge, and t is time measured from the instant at which the primary shock touches this tip, the flow pattern is stationary in similarity variables X/t, Y/t, (until the reflected shock strikes the upper wall of the shock tube). It is therefore assumed that the initial-value problem of this flow, when expressed in these variables, has the property that with almost any initial data the solution approaches the desired one as t w. Physical considerations suggest that if the initial flow pattern is not too far from the correct one this approach will be fairly rapid. This problem was selected for study in connection with a program of research [5] whose aim is the development of computing methods for fluid dynamics in two space variables and time. The general ideas of the program are. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
