Abstract
The enhancement of thermal conductivity of base fluids is desirable with the inclusion of nano-entities and bioconvection of microorganisms. The influence of the multi-slips on magnetohydrodynamic bio-convection streamline of micropolar based nanofluid across a sponge medium owing to expanding sheet is investigated in this work. The mass transpiration and activation energy with Fourier-Fick diffusion is taken into account. The leading partial differential equations are transformed into ordinary differential equations by using similarity transformations. The graphs were created by using the RK-4th order method with the shooting technique. Nusselt number, Sherwood number, skin friction factor, and motile density function are enumerated and analyzed with the variance of influenced parameters. It is observed the magnitude of the skin friction factor is enhanced with higher inputs of magnetic field and porosity parameters. Also observed that fluid speed is higher for injection than that of suction.
