Impact of Homogeneous/Heterogeneous Reactions and Convective Conditions on Peristaltic Fluid Flow in a Symmetric Channel

摘要

Simultaneous impacts of homogeneous and heterogeneous reaction and Joule heating in magnetohydrodynamic (MHD) peristaltic flowof viscous fluid in a symmetric channel are analyzed in this investigation.Attention has been focused on designing and simulating a mathematicalmodel for a viscous fluid in presence of viscous dissipation. Long wavelength approximation in wave frame analysis is implemented. Expressionsfor the stream function, axial pressure gradient, temperature, heat transfer coefficient and concentration are derived and discussed. In addition,the trapping phenomenon is analyzed. The effects of the physical quantities of concern are viewed with a special focus on homogeneous andheterogeneous reaction and convective conditions for the transfer of heatat the walls. It is observed that the pressure rise first increases and thendecreases with an increase in amplitude ratio. Effects of Brinkman andHartmann numbers on temperature are quite analogous and a temperaturerise is observed, however, temperature decays for the increased value ofBiot number. Moreover, fluid concentration decreases when the value ofthe homogeneous reaction parameter is increased.
