电致对流的实验研究及其应用

Experiments and Application on Electrically Induced Convection

当静电场作用于油液等介电流体时,将产生一些特殊的流体运动现象。根据流体力学知识和静电场理论,进行合理的流道设计和电极排布实验。实验表明,通过改变电场强度、流道形状、电极排布、油液含水量、杂质含量等,能够控制流动大小和方向的改变。将多个实验装置进行串、并联,可以制成电流体泵,实现电能到机械能的直接转换。

When the static electric field in the dielectric fluid oil,some special flow phenomenon will be produced.According to the theory of fluid mechanics and electrostatic field theory,experiments on reasonable flow of the design and arrangement of electrodes were made,and the orienteering of oil in the electric field gradient and under the drive of unipolar ions was also studied in this paper.Experimental results show that,by changing the electric field strength,channel shape,arrangement of electrodes,liquid water content and impurity content,the magnitude and the direction of the flow can be controlled.A number of experimental device in series and parallel can be made into current pump to realize the direct conversion from electric energy to mechanical energy.
