Abstract

Abstract: The motivation of current research is to explore thermo-bioconvection micropolar liquid flow subject to motile microorganisms and nanomaterials. Rheological model characteristics of Maxwell viscoelasticity-based micropolar nanoliquid are considered for analysis. Slip mechanisms and stratification phenomenon are accounted. Heat and concentration diffusions are characterized by exploiting the Cattaneo-Christov fluxes for heat and mass. Aspects of thermophoresis, thermal radiation and Brownian motion are also accounted. The dimensional non-linear boundary value problems are rendered into the dimensionless ODE's by utilizing admissible transformations and then tackled numerically by utilizing bvp4c technique via computational commercial software MATLAB. Significance of sundry variables against velocity, temperature, concentration of nanoparticles and microorganism's concentration are described through graphs and numeric data.
