RESUMO

In this paper, an analysis is presented to study the heat transfer characteristics of a micropolar fluid through an isotropic porous medium in a two-dimensional channel with rhythmically contracting walls. The flow analysis has been discussed under long-wavelength and low-Reynolds-number approximations. The closed-form solutions are obtained for velocity, microrotation component, heat transfer, and the stream function. Numerical computations have been carried out for the pressure rise per wavelength. The influence of various parameters of interest is seen through graphs of frictional forces, pumping, trapping phenomena, and temperature profiles.
