CONSIDERATION OF SIMULATION PARAMETERS FOR BLUNT THICK BODIES IN RAREFIED HIGH-SPEED FLOWS

Abstract

The current use of several different dynamic simulation parameters for correlating bluff body drag coefficient data is reviewed in terms of the need for a parameter which is both effective and does not contain any quantities whose values are uncertain in hypervelocity real-gas nonequilibrium flows. Such a nondimensional number or parameter is suggested and its effectiveness for correlating a variety of both previously published and new sphere drag data is assessed.
