Abstract

In this paper, motion of a flexible membrane and hydrodynamic INTERACTION of multiple membranes in amicrochannel are simulated by developing a computer code written in C. The membranes areconsidered as flexible boundaries immersed in the fluid. First, a single biconcave shaped membranewith high rigidity is considered. Due to the rigidity of the membrane, tumbling motion occurs andvertical displacement becomes oscillatory. Then, the effects of initial position of a circular membraneon its deformation, vertical velocity and displacement are investigated. It was observed that as the initiallocation of the membrane approaches the channel’s central axis, its vertical displacement and velocitydecreased, but its horizontal velocity component increased. Finally, the simultaneous motion of multiplemembranes in a MICROCHANNEL and their INTERACTION with each other and with flow are evaluated. Themembranes do not collide and hence the collision mechanism is not modeled. It was found that theupstream membrane experienced greatest deformation and the greatest force was exerted on it by thefluid on it. In addition, simultaneous presence of multiple membranes would result in a reduction in theflow velocity. The current numerical results have good agreement with the available valid numericalresults.
