dc.description.abstractHot flow model tests of multiple nozzle gas turbine exhaust eductor systems were conducted to evaluate the temperature effects of several eductor design modifications. A one-dimensional analysis of a simple eductor system based on conservation of momentum for an incompressible gas was used in determining the nondimensional parameters governing the flow. Eductor performance is defined in terms of these parameters. Compared to existing solid wall eductors, the addition of film cooling slots in the mixing stack, a mixing stack shroud and a double split ring diffuser section was found to significantly improve the pumping coefficient of the eductor, and drastically decrease all external surface temperatures as well as moderately reduce the maximum gas discharge temperature.
