Analysis of Vaneless Diffuser Stall Instability in a Centrifugal Compressor

Analysis of Vaneless Diffuser Stall Instability in a Centrifugal Compressor

Numerical simulations based on the large eddy simulation approach were conducted with the aim to explore vaneless diffuser rotating stall instability in a centrifugal compressor. The effect of the impeller blade passage was included as an inlet boundary condition with sufficiently low flow angle rel...
