Developing a Research Roadmap on Performance Limiting Flow Processes in High-Stage Loading Compressors

摘要

This document constitutes the final report on a research program on 'Developing a Research Roadmap on Performance Limiting Flow Processes in High- Stage Loading Compressors.' The focus is on developing the required research framework and tasks to address the fluid dynamic difficulties of highly loaded, high Mach number (HLHM) compressor stages. These consist of identifying the database available on such compressor stages, developing a plan to determine what additional data are needed, and defining the steps needed for successful execution of the research program in collaboration with the AFRL (Air Force Research Lab), NASA GRC and Rolls-Royce Inc. Indianapolis. The framework under which these tasks have been developed is based on hypothesis that the fluid dynamic difficulties encountered are linked to two specific flow processes in high-stage loading, high Mach number compressor stages.
