MEMS turbine cascade was designed and fabricated, in order to establish the cascade aerothermodynamics design method for MEMS turbomachinery, and clarify the mechanical behavior of compressible cascade blade-to-blade flow field in low Reynolds number regime. Stagnation pressure loss coefficient, blade Mach number, and the Zweifel parameter for the MEMS turbine cascade were determined. It is concluded that the stagnation pressure loss coefficient of the MEMS turbine cascade is several order larger than that of large counterpart. Therefore, significant penalty must be paid for the aerothermodynamic design of the MEMS turbomachinery.

设计并制作了MEMS涡轮叶栅，旨在建立MEMS涡轮机械叶栅空气热力学设计方法，明确低雷诺数状态下可压缩叶栅叶间流场的力学行为。确定了 MEMS 涡轮叶栅的停滞压力损失系数、叶片马赫数和 Zweifel 参数。结果表明，MEMS涡轮叶栅的停滞压力损失系数比大型涡轮叶栅的停滞压力损失系数大几个数量级。因此，MEMS 涡轮机械的空气热动力学设计必须付出巨大的代价。
