Have the hydrodynamic simulation models changed from previous versions?
A. Yes, updated hydrodynamic models are used in all software release versions. Specifically CORMIX1 and CORMIX2 simulation algorithms were modified for terminal level behavior in density stratified crossflow and for representation of the following asymptotic flow regimes: pure jet, pure plume, pure wake, and advected line puff. Additional details about the asymptotic flow regimes can be found in a paper by Jirka, 1999. The CORMIX3 simulation models were extensively revised replacing many near-field analytic solutions with an integral model approach. Also, CORMIX predictions are within +/- 50% of one standard deviation of available data. When comparing predictions, dilution S should be used for comparison not concentration. Furthermore, when comparing dilution S values, use the Logarithm of dilution S. All Log10(S) are well within the scatter of associated field and laboratory data. The CORMIX software is continuously updated with new and improved features, updated hydrodyhnamics, ruleb
