摘要

为解决增压发动机涡轮迟滞效应所带来的环境和操纵性问题，从实际使用角度出发，参考国内外的设计技术标准，采用轴流压气机的形式，为大功率发动机设计了一款在设计工况点流量为0.53 kg/s、总压比为1.3、等熵效率为86.95%的电辅助增压器.通过全三维数值模拟方法，对电辅助增压器的性能进行计算，得到流场细节和设计转速下的性能曲线，并对设计工况点和近失速工况点的流动状态和造成流动损失的原因进行分析.

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.

Key words： high loaded; turbo lag; electrically assisted turbocharger; axial compressor
