Abstract

In order to solve the environmental and maneuverability problems caused by turbocharged engine turbo-hysteresis effect, an electrical assisted turbocharger with flow rate of 0.53 kg/s at design point, total pressure ratio of 1.3 and isentropic efficiency of 86.95% was designed for high-power engine in the form of an axial-flow compressor referring to the design technical standards at home and abroad. The performance of the electroassisted turbocharger was calculated by full three-dimensional numerical simulation method, and the flow field details and the performance curve at the design speed were obtained, and the flow state at the design point and near stall point, in addition the cause of flow loss were analyzed.
