Double stratified analysis for bioconvection radiative flow of Sisko nanofluid with generalized heat/mass fluxes

With growing development in nano-technology and thermal engineering, nano-materials has intended a great interest of researchers in current decade due to their multidisciplinary significances in renewable energy systems, heating processes, industrial cooling circuits, hybrid-powered motors, solar systems, nanoelectronic, sensing and imaging, coating integrity, drug delivery , nuclear cooling systems etc. The study of nanofluids in presence of external thermal sources like thermal radiation, magnetic force, activation energy and heat source/sink is more effective to improve the heat and mass transportation mechanism. Following to such motivations in mind, current research concern with the bioconvection flow of Sisko nanofluid confined by a stretched surface subject to the bioconvection phenomenon. The applications of porous space and inertial forces are analyzed by employing the Darcy-Forchheimer relations. The modified Cattaneo-Christov relations are utilized to modify the heat and mass equations. The analysis is performed in presence of heat source/sink, activation energy and thermal radiation. The primarily cause and objective of this analysis to suggest more effective and generalized non-Newtonian nanofluid model containing the gyrotactic microorganisms. The developed system of equations are solved numerically by using the bvp4c shooting scheme by using MATLAB software. It is noticed that velocity profile increases with Sisko fluid parameter while it diminishes with local inertia coefficient and bioconvection Rayleigh number. An improve nanofluid temperature is observed with temperature ratio constant and Biot number. A lower nanofluid concentration is resulted due to higher values of Cattaneo-Christov mass flux constant and mixed convection parameter.
