Abstract

Our major focus in this analysis is to study the peristaltic motion of fluid by considering the homogeneous–heterogeneous reaction aspect. Prandtl nanofluid has been carried out for this purpose. Magnetic field is applied in the perpendicular direction to the flow. Joule heating effect is also considered in this analysis. Buongiorno nanofluid model has been used which incorporates two prominent slip mechanisms, i.e., Brownian motion and thermophoresis. The second law of thermodynamics has been utilized for entropy generation analysis. No-slip boundary conditions are employed for the considered analysis. NdSolve command of Mathematica 9.0 is employed for the solution of problem. Graphs for pertinent parameters are plotted and analyzed. These graphs contain velocity, temperature, homogeneous–heterogeneous reaction, entropy, and heat transfer coefficient. Key points of the investigation are collected in the conclusion.
