Electrokinetic Lift

叙述：首席研究人员在他的实验室中观察到了一种新的现象，称为电动升力：由两个带电表面滑动产生的流动电势产生的法向力，两个带电表面被一层薄的电解液溶液隔开。他建议对厚双层和薄双层的三维流动中胶体颗粒的电动升力进行分析和建模。这项研究的结果对润滑、流体动力层析、过滤和颗粒分离和沉积等过程具有重要意义。球-壁分离距离的变化是升力的指示，将使用一种名为全内反射显微镜(TIRM)的新技术来测量。为了本研究的目的，还建议开发TIRM。

Narrative: The principal investigator has observed in his laboratory a novel phenomenon called "electrokinetic lift": a normal force produced by a streaming potential generated by the sliding of two charged surfaces separated by a thin gap of electrolyte solution. He proposes to analyze and model electrokinetic lift of colloidal particles for three-dimensional flows for both thick and thin double layers. The results of this research are important to processes such as lubrication, hydrodynamic chromatography, filtration, and particle detachment and deposition. Changes in the sphere-wall separation distance, which are an indication of lift, will be measured using a new technique called total-internal-reflection microscopy (TIRM). It is also proposed to develop TIRM for the purposes of this research.
