Abstract
Flow mechanism of peristaltic motion is numerically and experimentally investigated to obtain a propulsive force in highly viscous fluid. Computing code for the analysis of the motions is developed with cell-centered unstructured grid scheme. The computed results by the developed code is compared with the experimental results which have been carried out to find out the propulsion mechanism in highly viscous fluid. The computed results shows good correlation with the experimental results and further the propulsive force can be obtained by sinusoidal motion which makes a pressure difference on waving surface. The more computation with variation of Reynolds number and parameters of motion is expected for finding a proper working range.
