Bioconvective MHD flow of tangent hyperbolic nanofluid with newtonian heating

Abstract

The main concern in this paper is to analyze the heat, mass and motile microorganisms transfer rate in the magnetohydrodynamic (MHD) convective flow of tangent hyperbolic material. Analysis is studied in presence of both nanoparticles past an exponential surface. Nanofluid containing gyrotactic microorganisms in addition to nanoparticles is considered. Analysis is carried out in presence of an inclined magnetic field. In fact the idea here is to use the microorganisms just to stabilize the suspended nanoparticles due to bioconvection generated by the combined effects of buoyancy forces and magnetic field. Brownian motion, thermophoretic and Newtonian heating are also studied. The resulting systems of nonlinear systems have been solved by homotopic procedure. The velocity, temperature, nanoparticle concentration and density of motile microorganisms are examined graphically. The skin friction coefficient, local Nusselt, Sherwood and motile microorganism numbers are numerically discussed for the active involved parameters. It is observed that velocity profile is decreased by both magnetic parameter and angle of inclination. It is also noted that the temperature profile increases for larger Nb but it decreases for nanoparticle concentration.
