In this paper, a comparative study between numerical and experimental results from
PIV measurements is presented in the case of two-dimensional electrohydrodynamic plumes that arise when a sharp metallic blade, submerged in non conducting liquids, supports high electric potential. Experiments and numerical simulations have been conducted in order to confront the both approaches. A very good agreement has been found through velocity profiles and velocity fields which testifies the relevance of our numerical model. For high potentials the jet flow issued forth from the blade becomes unsteady and starts to flap on the vertical wall. Some captions of the temporal evolution of the isocontours of charge density which is not accessible from experiment are presented thanks to the numerical simulation.

     FlowMaster 显微PIV系统设计用来测量微米级空间分辨率下示踪颗粒速度场。它利用粒子成像测速原理，将常规 PIV 应用拓展到微尺度范围。
     系统采用双脉冲Nd:YAG激光作为光源，通过大数值孔径光圈荧光显微镜聚焦到微流动模型上。微流动采用荧光颗粒作为示踪物，通过显微镜采集到的颗粒散射光的波长比入射光波长要长。由于波长不同，这个光波信号通过一个滤波透镜与入射光分离开，并由FlowMaster系列相机拍摄下来。双曝光产生的颗粒图像，经过高级精密的PIV算法处理后获得微尺度流场的速度场结果。
