Abstract:

The primary purpose of the Exhauster System of the Transonic Turbine Test Rig of the United States Naval Postgraduate School, Monterey, California, is to increase the range of turbine operating pressure ratios by maintaining a partial vacuum inside a hood that encloses the turbine. The first part of this study is concerned with the design and the tests of the exhauster system. The experiments were used to establish a method of predicting the operating characteristics of similar ejectors which is based on the universal ejection properties of turbulent jets. The second part of this study describes turbine tests utilizing the exhauster system that were carried out to investigate the effects of high values of the isentropic head coefficient and Reynolds number on the turbine performance. No correlation could be established between turbine Reynolds number and performance in the range tested. Author
