The Navier-Stokes equations are solved numerically for two-dimensional perstaltic flows by using the finite-difference technique employng the upwind SOR method, and pumping characteristics of peristaltic transport are studied. The energy transfer in the flow and the mechanical dfficiency of the peristaltic pumping are analyzed in this paper, for a wide range of wave amplitudes, wavelengths and Reynolds numbers. The effectts of variations of these parameters on the pumping characteristics are investigated. And the trapping phenomenon which is an peculiar pattern in the peristaltic are also investigated in detail, in order to study the contribution of the trapping to the hydrotransport of peristaltic pumping. As a result, it is found that the pumping efficiency is caused to increase remarkably by increasing of wave amplitude, but is slightly reduced by the effect of fluid inertia as Reynolds number increases.
