Research Summary
Turbine Heat Transfer & Aerodynamics: Using fully scaled experiments on a high speed turbine stage & CFD simulation, we are exploring the fluid physics of advanced transonic turbines, currently looking at the role of inlet temperature non-uniformity on turbine operation.
Advanced Diagnostic Instrumentation: We are trying to improve the detail & accuracy to which the flow in turbomachinery can be measured. One current project is the development of an instrument to optically measure gas temperature in compressors & turbines using laser induced fluorescence of 02.
Turbomachinery Noise: The many sources of noises in turbomachinery are not well established quantitatively. An experimental investigation of noise sources in centrifugal pumps is pursuing this question.
Environmental Impact of Aircraft: MIT is beginning a major initiative, exploring the impact of aircraft on the atmosphere, the role aircraft & engine design can have on mitigating that impact, and the effects on air transportation economics.
