Constant Parameter Two Component Channel Flows,

Abstract

Johnson and Von Ohain proposed the RHEA concept for accelerating air to velocities significantly greater than that produced by expanding heated air from a reservoir. The RHEA process employs a low molecular weight gas to accelerate a dense particle cloud to very high velocities which is then separated and introduced into an expanded air stream which is then further accelerated by the drag of the particle cloud. The air is cleaned prior to its entry into the wind tunnel test section. This paper examines constant parameter, two component channel flows as a basis for designing the air acceleration section. Results demonstrate that a constant static air temperature channel would be a useful choice for producing high Mach number, high recovery pressure flows for testing reentry missile nose tips.
