Investigation on the Flow Angle of a Mixed Flow Turbocharger Turbine Under Steady State Operating Conditions Authors

Turbocharger is widely used in automotive field for the capability to extract or boost downsizing internal combustion (IC) engine as it has been considered a way provide highly efficient of small engine. also reduces fuel consumption well carbon dioxide (CO2) emission. Turbine one main components turbocharger. Generally, this study mainly focusing on mixed flow turbine that work under steady operation. Numerical using Computational Fluid Dynamics (CFD) presented report. This report aims compare angle analysis three selected cases state operating conditions. A 3D modelling generated accordingly ‘Rotor A’ design by commercial software Ansys CFX. Three were order at mid span circumference location vane and rotor inlet. The simulation results show capabilities model developed capturing trend available experiment data speed 48kRPM. achieves optimum total-to-static efficiency 74.16 % velocity ratio 0.65 with mass rate 0.5kg/s. Besides that, shown distribution inlet varied throughout between cases. Case 2 achieved incidence compared other thus showing impact determining performance.
