Results were not obtained by usingthe LAURAcodeforlongbodiesduetothe excessive computational time required for such calculations. From the results presented in Figs. 4-6,itisobviousthat theuse ofhigher-orderbodyand shock slip conditionswith the HVSLequations avoids the need for costly and time-consuming Navier-Stokes calculations 2*16,to study new technology areas. The HVSLresults typically require less computational time (as compared with a LAURAcalculation)byafactor ofabout 5to 10 depending on the flowfield chemistry and length of the body, with larger computational times required for nonequilibrium flows and longer bodies.
