MHD bioconvection microorganism nanofluid driven by a stretchable plate through porous media with an induced heat source

Abstract

Nanofluids contains tiny particles in the working liquid due to which heat conduction is raised appreciably. Further, existence of the motile microorganisms boosts the thermal and mass transport in the system and so the improvement is developed in the stability of nanofluid. In this perspective, the emphasis of the existing analysis is to explore the effect of magnetism on the stream bioconvection nanoliquid via porous media under the influence of heat radiation driven by stretching surface. The present flow situation of PDEs is remodeled invariantly to nonlinear ODEs using similarity variables. Further, classical Keller-box technique is implemented to deal with the transformed model. The physical characteristics of flow restrictions over velocity, energy, concentration and density profile are plotted and discussed. With elevation in porosity, thermal buoyancy and slip boosted the microorganism nanofluid flow velocity. Due to induced electromagnetic force velocity is reduced with rise of magnetic term. Except Prandtl number all the considered thermofluidic terms encourages heat propagation and diffusion. A strong boost in species mass distribution is observed with an increase in thermophoretic term due to high propelled of the chemical reaction. Overall magnitude of the microorganism motile density is damped for various examined thermophysical parameters.
