Hot Flow Testing of Multiple Nozzle Exhaust Eductor Systems.

Abstract

Hot flow model tests of multiple nozzle exhaust eductor systems were conducted to evaluate effects of exhaust temperature on eductor performance. A one-dimensional analysis of a simple eductor system based on conservation of momentum for an incompressible gas was used in determining the non-dimensional parameters governing the flow phenomenon. Eductor performance is defined in terms of these parameters. An experimental correlation of these parameters which was previously developed and used to correlate cold flow data was found to be effective in correlating both cold and hot flow data for eductor systems. Temperature data was obtained for the mixing stack wall and the exhaust flow at the mixing stack exit plane. (Author)
