✦ Synopsis

A quantitative analysis of solutions to the Euler equations of fluid dynamis with the MUSCL, ENO-Harten, and efficient ENO-Shu algorithms is performed. Investigations of different test problems in one and two dimensions are presented. These are chosen as to model the shock-turbulence interaction in fluid dynamical systems. The notion of subcell resolution developed by Harten for the ENO schemes slearly improves the solution in one dimension; however, the effect is less prominent in a Strang-type extension to two dimensions. Our results confirm the superiority of the ENO schemes over the MUSCL approach in solving problems of flow fields with discontinuities which, at the same time, contain fine structure in its smooth parts. 1995 Acadernic Press, Inc.

An algorithm is proposed for the computation of the Mann-Whitney Test which only requires the separate ordering of the individual samples and is therefore more suitable than the usual one. It is also more suitable as t o computation time than the algorithm described by KUMMER, 1981, if the two sampl

## Abstract A simple gasdynamic model, called CHEMSHOCK, has been developed to predict the temporal evolution of combustion gas temperature and species concentrations behind reflected shock waves with significant energy release. CHEMSHOCK provides a convenient simulation method to study various siz
