NONLINEAR THERMAL RADIATION AND ACTIVATION ENERGY EFFECTS ON BIOCONVECTIVE FLOW OF EYRING-POWELL FLUID

The dynamics of Eyring-Powell nanofluid suspended with microorganisms on a plate, wedge, and stagnation point is explored. The flow field is influenced by nonlinear thermal radiation, activation energy, and bioconvection. The governing equations are modified into a system of ordinary differential equations (ODE) by similarity transformation, which are numerically solved through the R-K shooting method. This study addresses the effect of various pertinent factors on the fluid flow, mass, and heat transfer characteristics, which are elucidated via graphs and tables. It is witnessed that the Eyring-Powell (EP) fluid material parameters lambda(l) and lambda(2) exhibit a contrary nature on the velocity profiles. Improved values of Prandtl number magnify the heat transfer. Larger values of Schmidt number weaken the concentration boundary layer. The density of microorganisms depreciates for growing values of Peclet number and bioconvective Schmidt number.
