Gyrotactic bioconvection stratified flow of magnetized micropolar nanoliquid configured by stretchable radiating surface with Joule heating and viscous dissipation

Nanotechnology attracts a significant consideration owing to its enormous utilizations in cancer treatment, medicine, nano-metric pregnant, nano-tubes metric, nano-robot, bio-nano-metric devices, aircraft industry, water desalination and rubber metal. Keeping such astonishing utilizations in view, the prime idea of this analysis is to scrutinize the effectiveness of radiation aspect in magnetized micropolar nanoliquid configured by impermeable stratified surface. Micro-organisms concept is adopted to stable the adjourned nano-particles via bioconvection impact persuaded by simultaneous consideration of magnetic field and buoyancy forces. In addition, the aspects of chemical reaction, Joule heating, Brownian motion, viscous dissipation and thermophoresis characteristics are analyzed. The modeled non-linear problems are simplified through boundary-layer concept. Non-linear problems are tackled analytically through homotopy scheme. The pictorial representations illustrating features of distinct emerging variables on dimensionless quantities are described comprehensively. It is investigated that stratified (thermal, solutal and motile density) variables yield lower distributions of thermal, solutal and motile micro-organisms density respectively.
