Peristaltic flow of an Eyring Prandtl fluid in a diverging tube with heat and mass transfer

Abstract

The present article reflects the peristaltic motion of an Eyring Prandtl fluid in a diverging tube in the presence of heat and mass transfer. Mathematical Analysis has been carried out by considering the assumptions of long wave length and low Reynolds number. Under these limitations, we obtain resulted non linear system of small values. These have been evaluated analytically using homotopy Perturbation method. The succeeding complex disparity computations are explained for velocity, temperature, concentration field and pressure gradient. The effects of physical parameters on the flow and heat transfer attributes are investigated in detail. Special attention is given to explain the pumping and trapping phenomena in detail. Convergence of solution is clearly shown in the graphical results. It is found that rate of heat transfer and mass transfer decreases with increasing Brashof number. The consequence of many underdeveloped restraint are explicate for five dissimilar impressions. Streamlines in trust at the terminus point of the objective.
