Abstract
This communication deals with the numerical investigation of bioconvection induced by an unsteady MHD stagnation point flow of a nanoliquid containing suspension of microorganisms over a stretching sheet. The sheet is stretched in an exponential fashion and set at the right side of porous medium saturated with nanofluid, and permeability of porous medium is considered to have a specified form. The setup deals with the velocity slip and thermal slip at the sheet surface. Here, water is considered as the carrier liquid. Similarity transformations are used to convert the governing coupled nonlinear partial differential equations into ordinary differential equations and solved numerically by employing implicit finite difference scheme known as Keller box method. The effects of nanofluid parameters and bioconvection parameters on non-dimensional velocity, temperature, nanoparticle concentration, and motile microorganism concentration are presented through graphs. The effects of related parameters on local skin friction, Nusselt number, Sherwood number, and density number of microorganisms are exhibited through tables. The substantial influence of bioconvection parameters is noticed on the profiles of velocity, temperature, nanoparticle volume fraction, and density of microorganisms.
