A numerical procedure for the analysis of one-space-dimensional non-steady compressible flow
Abstract
The considered procedure is based on the method of characteristics and is inherently suitable for a wide range of one-dimensional, nonsteady, compressible flow problems. Three basic steps required to establish the differential equations needed for the analysis are discussed, taking into account conservation equations, thermodynamic relations, and Riemann variables. Attention is given to the resultant equations, the numerical solution procedure, and an application to shock-tube problems. The investigation shows that the considered procedure can be applied, with reasonable accuracy, to situations in which there is an entropy discontinuity and also where frictional and heat transfer effects are relatively significant.
