Investigation of natural bio-convective flow of Cross nanofluid containing gyrotactic microorganisms subject to activation energy and magnetic field

The aim of current communication is to investigate the flow features of Cross nanomaterial over stretched porous surface subject to activation energy and magnetic field. The idea of gyrotactic microorganisms is used to stabilize the nanoparticles in Cross fluid. Temperature relation is modeled considering thermal radiation and viscous dissipation. Furthermore, Bio-convection through mutual effects of thermophoresis and Brownian diffusion is also considered. Boundary layer assumptions are used to obtain the flow expressions. The obtained flow expressions are transformed into non-dimensional one using similarity transformations. Newton built in shooting technique code in Mathematica software is implemented to study the impact of potential parameters on velocity, temperature, concentration and concentration of microorganisms. Numerical computations for physical quantities such as skin friction, Nusselt, Sherwood and density numbers are also discussed. Important observations are highlighted at the end.
