AN INVESTIGATION OF THE PERFORMANCE AND MIXING PHENOMENA ASSOCIATED WITH A SUPERSONIC EXHAUSTER INTERACTING WITH SUBSONIC SECONDARY FLOW.
Abstract
The Transonic Turbine Test Rig uses a supersonic jet exhauster to lower the turbine exit static pressure and thus increase pressure ratios available for turbine testing. Exhauster operation results in interaction between two co-flowing streams of air. The primary air is supersonic and the secondary air, subsonic. This thesis is an experimental study of the mixing process that occurs between the two streams in a cylindrical mixing chamber. In addition, a theoretical model of the exhauster performance based on polytropic efficiencies and conservation of momentum was programmed, and the predicted values were compared to test results.
