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 M.I.T. 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 techniques for use in transonic fans) (2) Studies of basic mechanisms of compressor stability enhancement using compressor casing/hub treatments ; (3) Fluid mechanics of inlet vortex flow distortions in gas turbine engines; (4) Investigations of three-dimensional flows in highly loaded turbomachines (including blade-to-blade flow analysis and numerical computations of secondary flow in a bend using spectral methods. In addition to these tasks, this multi-investigator effort also includes the Air Force Research in Aero Propulsion Technology (AFRAPT) Program.
