THREE-DIMENSIONAL ANALYSIS OF THE CONCENTRATION IN AN ELECTROPHORESIS CHAMBER WITH CONTINUOUS FLOW
连续流式电泳浓度场的三维分析

This paper studies the separation process of different particles in a suspension continuously flowing through a square electrophoresis chamber under the action of a transverse electric field. Three-dimensional temperature, velocity and concentration fields as well as their interactions are taken into consideration, for the first time, and the effects of various parameters under micro-gravity and usual gravity are demonstrated through numerical simulations. A new quasi-three-dimensional approach is proposed, which can yield results in agreement with those by a true three-dimensional approach, but with much less computational efforts.
