Abstract

A general design formula for rotor profile is proposed based on conjugation theory and feasibly verified by using the four different design shapes. The overset mesh method and the realizable k-ε two-layer turbulence model are used for simulation calculation. The results stated that the average volume flow error of hydrogen medium and air medium is small, so an alternative experimental study has been carried out. By building a test system for experimental verification, it is found that the error between the simulation results and the experimental results is small at the low-pressure ratio and increases at the high-pressure ratio because the influence of the ambient temperature is not considered. The results further verified the reliability using the simulation calculation method. At last, the fluid characteristics of the two-tangent-arcs type, single-arc type, ellipse type, and quadratic-curve type rotors are evaluated. The result shows that the comprehensive performance of the single-arc type rotor is superlative as followed by the ellipse type rotor. However, the quadratic-curve rotor has the largest average flow but the worst flow stability and the two-tangent-arcs rotor shows the smallest average flow.

燃料电池系统氢循环泵外形设计及性能研究
基于共轭理论,提出了转子型线的通用设计公式,并用四种不同的设计型线进行了可行性验证。采用复盖网格法和可实现的k-ε双层湍流模型进行仿真计算。结果表明,氢气介质和空气介质的平均体积流动误差较小,因此进行了替代实验研究。通过搭建测试系统进行实验验证,发现在低压比下,仿真结果与实验结果的误差较小,在高压比下,由于不考虑环境温度的影响,仿真结果与实验结果的误差增大。结果进一步验证了仿真计算方法的可靠性。最后,对两切弧型、单弧型、椭圆型和二次曲线型转子的流体特性进行了评价。结果表明,单圆弧型转子综合性能最好,其次是椭圆型转子。二次曲线转子的平均流量最大,但流动稳定性最差,两切弧转子的平均流量最小。
