【摘要】 <正> 一、前言 发展高负荷涡轮,进行气动设计,需要做大量的气动实验和计算研究,这就需要发展先进的实验设备、测试技术和数值计算方法。跨声速涡轮的流场,高压、高温、高速,有激波,激波与边界层相互作用将产生分离。对此种复杂流动现象,测量技术难度大,数值计算模型也复杂。因此,数值计算研究与实验研究紧密结合,互相促进,互为补充理应得到更多还原

【Abstract】 Transonic turbine cascade flow on S1 surface was calculated by stream function equation with the direct matrix method. Pressure data on blade surface were measured by pressure transducer, and density data of the flow field were measured by differential interferometer in a shock cascade tunnel. The predicted results agreed well with the measured results so that the numerical method and computer program may be used to predict cascade flow of transonic turbine.更多还原
