| Abstract: | A new method of a centrifugal compressor with a huh airfoil-vane diffuser was proposed and applied based on the investigation of a centrifugal compressor with vaneless diffuser. The results show that the flow in the hub airfoil-vane diffuser with certain vane height is better than that in a vaneless diffuser. It prove that the hub airfoil-vane diffuser can improve the performance of a compressor with a vaneless diffuser. |
