ABSTRACT CTS-0307099A. Acrivos, CUNY City CollegeThe primary goal of the NSF proposal is to study theoretically and experimentally the interaction of suspended particles with a traveling electric field having a constant amplitude. This interaction originates through the time lag of the polarization of the particles and the suspending fluid due to the spatial variation of the field phase in a traveling electric wave. This project will address electro-hydrodynamic phenomena originating through the imaginary components of the polarization of particles and a suspending fluid, which are responsible for the loss of the electric energy. In particular, a traveling electric field was observed to drag a fluid whereas a high gradient electric field whose phase is constant does not generate the fluid flow.

摘要CTS-0307099A。NSF计划的主要目标是从理论和实验上研究悬浮粒子与恒定振幅的行进电场之间的相互作用。这种相互作用源于行波中场相空间变化引起的粒子和悬浮流体极化的时滞。该项目将解决由粒子和悬浮液的极化虚部产生的电流体现象，这些虚部是造成电能损失的原因。特别是，观察到行波电场对流体的拖曳作用，而相位恒定的高梯度电场不会产生流体流动。
