在本文中，通过实验测量和数值模拟对带有两级电流体动力（EHD）气泵的方形通道内的流场进行了严格的研究。每级都有 28 个发射电极的 EHD 气泵经过了从电晕起始电压到高达 28 kV 的各种工作电压的测试，以进一步提高其性能，使其优于单级气泵。事实证明，两级 EHD 气泵可以产生并维持最大速度为 1.8 m/s 的气流。其最大性能为36 L/s/W，优于个人电脑中使用的传统冷却风扇。还讨论了其在热管理和强化传热中的应用的意义。
In this paper, the flow field inside a square channel with a two-stage electrohydrodynamic (EHD) gas pump has been critically examined by experimental measurement and numerical simulation. The EHD gas pump with 28 emitting electrodes in each stage is tested for a wide range of operating voltages starting from the corona onset voltage up to 28 kV for further improvement in its performance over a single-stage one. It has been shown that the two-stage EHD gas pump can produce and sustain gas flows with a maximum velocity of 1.8 m/s. Its maximum performance of 36 L/s/W is better than that of conventional cooling fans used in personal computers. The implication for its application in thermal management and heat transfer enhancement has also been discussed.
