| Popis: | The study of nanofluid dynamics under the influence of bioconvection has valuable applications as the nanofluids possess tremendous heat transfer capabilities in comparison to the ordinary fluids. Having such amazing characteristics of nanofluids in mind, the objective of the present study is to analyze the influence of bioconvective Micropolar nanofluid flow comprising gyrotactic microorganisms with the thermal and solutal stratifications at the boundary surface. The novelty of the present study is enhanced by adding the contribution of nonlinear thermal radiation with partial slip boundary condition. The Homotopy Analysis Method (HAM) is employed to address the highly nonlinear system of differential equations. This system of differential equations is an outcome of suitable transformations applied to the mathematical model described by the system of partial differential equations. Illustrations depicting influences of prominent parameters are supported by requisite discussions keeping in view their physical significance. It is comprehended that the local density number is deteriorated for Peclet and bio-convection Lewis numbers. It is also observed that fluid velocity is declined for growing estimates of bioconvection Rayleigh number. |
