On Two-Dimensional Flows of Compressible Fluids (open access)

On Two-Dimensional Flows of Compressible Fluids

"This report is devoted to the study of two-dimensional steady motion of a compressible fluid. It is shown that the complete flow pattern around a closed obstacle cannot be obtained by the method of Chaplygin. In order to overcome this difficulty, a formula for the stream-function of a two-dimensional subsonic flow is derived" (p. 1).
