Abstract: The unsteady behavior and threedimensional flow structure of spiketype stall inception in an axial compressor rotor were investigated by experimental and numerical analyses. Previous studies revealed that the test compressor ...

Abstract: Recently, the application of turbochargers is increasing because they are effective in improving fuel consumption of engines. One of the most important turbocharger characteristics is compressor operating range, since it ...

Abstract: Turbulence is one of the most important phenomena in fluid dynamics. Large eddy simulation (LES) generally allows us to analyze smaller eddies than when using simulations based on unsteady Reynolds-averaged Navier–Stokes ...

Abstract: This paper describes the flow mechanisms of rotating stall inception in a multistage axial flow compressor of an actual gas turbine. Large-scale numerical simulations of the unsteady have been conducted. The compressor ...
