Influence of MHD on mixed convective heat and mass transfer analysis for the peristaltic transport of viscoplastic fluid with porous medium in tapered channel

Abstract

In this paper, the influence of magnetohydrodynamic (MHD) on a mixed convective heat and masstransfer analysis for the peristaltic transport of viscoplastic fluid in a non-uniform two dimensionaltapered asymmetric channel with porous medium is investigated. The governed equations thatdescribed the motion of flow are simplified under assumptions of low Reynolds number and longwavelength. These equations are solved by mean of the regular perturbation method which is restrictedto the smaller values of Bingham and Grashof numbers. Series solution for the axial velocity,temperature and concentration distribution have been computed. The flow quantities have beenillustrated graphically for different interesting parameters. The trapping phenomena is also examinedgraphically.
