摘要: This work outlines a procedure for simulating the flow field within multistage turbomachinery which includes effects of unsteadiness, compressibility, and viscosity. The associated modeling equations are average passage equation system governs time-averaged typical blade row embedded configuration. results from simulation low aspect ratio stage one-half turbine will be presented compared with experimental measurements. It shown that secondary generated by rotor causes aerodynamic performance downstream vane to significantly different an isolated row.Copyright © 1989 ASME
