Radiative slip transport of magnetized gyrotactic micro-organisms submerged with nano fluid along a vertical stretching surface with suction/injection effects

Abstract

Micro-organisms play an important role in numerous conditions such as toxin release, digestion and antibiotics. These remarkable features of motile organisms can lead to bio convection phenomena. Keeping in view, the present article is focused to study the collective impact of motile organisms and nanoparticles on flow past an elastic porous surface. Thermal radiation, viscous dissipation and prescribed surface slip condition is also imposed in order to acquire physically realistic analysis. The flow governing problem is modeled using fundamental laws of momentum and energy which afterward is transformed by utilizing a suitable scaling analysis. Role of emerging sundry parameters on quantities of physical interest are portrayed graphically and discussed in a physical manner. It is observed that fluid’s velocity and temperature rises for radiation parameter but concentration of fluid drops down. Local motile density slightly enhances with Dissipation, Suction and Radiation factor while it drops down with Slip factor. When injection of fluid raised then skin friction coefficient, Nusselt number, Sherwood number and motile microorganism density also raised.
