Computational Design Sensitivity Approach for Transonic Compressor Passive Flow Control

What is it about?

The development of a design tool for self-recirculating compressor flow control simplifies the design and analysis process by employing physically realistic boundary conditions, eliminating the need for a physical realization of the geometry. This paper outlines the process of simplified passage design, addressing key challenges and constraints encountered in developing such a tool. Several studies were conducted on the NPS Transonic Compressor Rig (TCR) to evaluate the impact of design parameters on compressor performance. The analysis includes detailed flow field assessments, speedline generation near stall, and an evaluation of the effects on stall margin.

Why is it important?

This approach enables a faster and more efficient flow optimization process for self-recirculating compressor flow control. The optimized flow recirculation passage can be integrated into an actual compressor, enhancing engine safety and reducing the risk of stall-related failures, thereby improving aircraft crew safety. Additionally, it ensures greater reliability and performance in military propulsion systems.
