Abstract:

Theoretical real gas performance calculations were made for the expansion tunnel operating in a high density regime at modest velocity. Both Mach number-Reynolds number simulation and flow duplication were considered. Typical results and detailed working graphs are presented. To illustrate the potential of the expansion tunnel, the performance was calculated for the case of a 1000K, 5000-atm helium driver. This example illustrates that the expansion tunnel does show promise for testing in the high density regime at modest velocity.
