Abstract
Due to the axial asymmetry of the volute structure, the circumferential inhomogeneity of the flow at the volute outlet exists, leading to the deviation of the flow in the nozzle and impeller from the ideal state. In this paper, a numerical study of a SCO2-radial inflow turbine is carried out to simulate the flow inside the turbine with the asymmetric and symmetric volute respectively. The results show that the use of a pear-shaped symmetric cross-section volute can effectively reduce the circumferential inhomogeneity of the flow, simplify the vortex structure inside the volute, reduce the flow losses and improve the efficiency of the turbine.
