Abstract
Simultaneous impacts of homogeneous and heterogeneous reaction and Joule heating in magnetohydrodynamic (MHD) peristaltic flow
of viscous fluid in a symmetric channel are analyzed in this investigation.
Attention has been focused on designing and simulating a mathematical
model for a viscous fluid in presence of viscous dissipation. Long wavelength approximation in wave frame analysis is implemented. Expressions
for 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 and
heterogeneous reaction and convective conditions for the transfer of heat
at the walls. It is observed that the pressure rise first increases and then
decreases with an increase in amplitude ratio. Effects of Brinkman and
Hartmann numbers on temperature are quite analogous and a temperature
rise is observed, however, temperature decays for the increased value of
Biot number. Moreover, fluid concentration decreases when the value of
the homogeneous reaction parameter is increased.
