Abstract
For many compressible flow applications entropy and entropy production are critical indicators of the state of the gas. This is especially true for flows in which the gas may experience thermal nonequilibrium or chemical reactions which change its composition. This presentation outlines a method of calculating entropy for small perturbations, which may be treated as a matrix normalization for calculating the L2 norm of small perturbations, as well as a method of calculating the total entropy production of compressible nonequilibrium flows. The utility of these relationships is demonstrated with several test cases, and the significance of the results obtained as they relate to existing methods and metrics is discussed.
