摘要：
A two-dimensional unsteady numerical simulation using Immersed Boundary method is carried out to investigate the fluid flow and heat transfer characteristics in a channel of peristaltic micro pump. The heat transfer target wall is a portion of the immovable top wall, while the rest of the wall including the movable bottom wall with fluctuating in the form of a sinusoidally progressive wave maintains the adiabatic condition. The obtained result shows a pair of large-scale recirculation in the case of relatively larger amplitude enhances the convection heat transfer and reduces the size of reverse flow region near the target wall.
