摘要
针对某增压器原机高原适应性不足的问题,开展了一维初始目标设计和详细的三维流动仿真分析,对车用跨声速离心压气机进行了高原适应性改进设计。通过降低叶片后弯角、增加叶片数进而增加叶轮做功能力来提升压比。通过叶片细节设计,包括分流叶片前掠和出口曲线掠型进一步优化压气机性能,最终通过了试验验证,在原机的基础上成功优化设计了高压比离心压气机,满足了发动机的使用需求。
One-dimensional initial target design and detailed three-dimensional flow simulation analysis were carried out to improve the poor plateau adaptability of vehicle transonic centrifugal compressor.The working ability and pressure ratio of impeller improved through reducing the back sweep angle and increasing the number of blades.The performance of the compressor was further optimized through the detailed design of the blade such as the forward sweep of splitter blade and the curve sweep of blade outlet.The performance of the compressor was further verified by the bench test.Accordingly,the high-pressure ratio centrifugal compressor was successfully designed,which met the requirements of the engine.
