Current problems in turbomachinery fluid dynamics
Abstract
A multi-investigator program on problems of current interest in turbomachinery fluid dynamics is being conducted at the MIT Gas Turbine and Plasma Dynamics Lab. Within the scope of this effort, four different tasks, encompassing both design and off-design problems, have been identified. These are: (1) Investigation of fan and compressor design point fluid dynamics (including formation of design procedures using current three-dimensional transonic codes and development of advanced measurement techniques for use in transonic fans); (2) Studies of basic mechanisms of compressor stability enhancement using compressor casing/hub treatment; (3) Fluid mechanics of inlet vortex flow distortions in gas turbine engines; and (4) Investigations of three-dimensional analytical and numerical computations of flows in highly loaded turbomachinery blading.
