Abstract

Rapid advancement in microelectronics requires efficient component cooling. In this study, the effects of emitting electrodes on the performance of a two stage electrohydrodynamic (EHD) gas pump are evaluated by experiment and numerical simulations. A two stage EHD gas pump with 8 emitting electrodes is evaluated and the results are compared with 24 and 56 emitting electrodes configurations. It is evaluated for a wide range of operating voltages starting from 20 kV up to 28 kV. The emitting electrodes of the pump are flush mounted on the channel walls so that the corona wind produced directly disturbs the boundary layer thickness. This is leading to a higher velocity near the channel walls and resulting in an inverted parabolic velocity profile at the center of the channel, which is opposite to the fully developed velocity profile of a forced flow. Velocities are measured at three cross-sections along the tube length and then integrated to obtain the volume flow rate.

发射电极数对两级电液动力气泵性能的影响

微电子技术的快速发展需要高效的元件冷却。通过实验和数值模拟，研究了发射电极对两级电液动力（EHD）气泵性能的影响。对具有8个发射电极的两级EHD气泵进行了评价，并与24个和56个发射电极的配置进行了比较。它的工作电压范围从20千伏到28千伏。泵的发射电极平齐安装在通道壁上，使得产生的电晕风直接扰动边界层厚度。这导致通道壁面附近的速度更高，并导致通道中心的速度曲线呈倒抛物线状，这与强迫流动的完全发展速度曲线相反。沿着管道长度在三个横截面测量速度，然后积分得到体积流速。
