Peristaltic flow of a micropolar fluid in an asymmetric channel
نویسندگان
چکیده
In this paper, we carry out a study of peristaltic motion of an incompressible micropolar fluid in an asymmetric channel. The flow analysis has been developed for low Reynolds number and long wavelength case. Exact analytic solutions have been established for the axial velocity, microrotation component and stream function. Expression for the shear stresses are also obtained. The effects of pertinent parameters on the pressure rise per wavelength are investigated by means of numerical integration. The phenomena of trapping is further discussed. The results for micropolar fluid are compared with those for Newtonian fluid. c © 2007 Elsevier Ltd. All rights reserved.
