Proc. ASME. GT2023, Volume 13A: Turbomachinery — Axial Flow Fan and Compressor Aerodynamics, V13AT29A035, June 26–30, 2023
Publisher: American Society of Mechanical Engineers
Paper No: GT2023-103218
... Abstract Shock waves and their interaction with the boundary is a significant flow effect within transonic compressor blading. The main challenge here is the unsteady nature of this interaction effect because it imposes further requirements to maintain the structural integrity of the blading...
