Abstract In this paper, micro-turbine centrifugal impeller with three different blade angles was investigated
by using Computational Fluid Dynamics (CFD) method. The other basic geometric parameters are held
constant. The influence of the blade angles change on the observed values was determined from
numerical solution of the flow in the impeller with help of the FLUENT software. The numerical
simulation focused on the air flow from compressor impeller inlet to exit, and the performance of
impeller is predicted. The numerical solution was performed for original impeller geometry and for
two other cases, in which blade inlet angle and backward sweep was… More >
