Computational Science and Engineering Advances Understanding of Complex Unsteady Flows in High Performance Fans and Compressors

Abstract

The ability of high fidelity simulations to more accurately model complex flow phenomena in high performance military fans and compressors is demonstrated. Challenge Project CII continues to investigate how blade row interactions and distortion transfer impact fan and compressor performance. Simulations accomplished through this Challenge Project have produced improved geometric, physical, and numerical fidelity results than previously possible, allowing the design of next generation engines to achieve unprecedented performance
