Chemically reactive micropolar hybrid nanofluid flow containing motile microbes over stretching sheet with Cattaneo–Christov heat flux model

Abstract Objective/Novelty: The flow of microbial cells in a fluid affects a number of biotic processes, such as the ecology of marine life and septicity. It is necessary to investigate the mechanism of nanofluids containing a microbial suspension for several chemical and medical applications. The current communication concentrates on the magnetohydrodynamic (MHD) Micropolar nanofluid flow past stretching sheet with Cattaneo–Christov heat flux theory and motile microorganisms. The influence of Soret and Dufour on hybrid nanofluid has been carried out. The nature of Copper and Ferrite with water base fluid is executed in this analysis. The Darcy's law of porosity is used for the modeling of porous medium. The energy equation is explored in the occurrence of nonlinear thermal radiation and heat source parameter. Design/Methodology/Approach: The partial differential equations are transformed to couple ordinary differential equations with the aid of similarity transformations. The dimensionless equations are numerically solved by utilizing the Bvp4c solver with shooting technique. To compute the code of modeling computational software MATLAB is used. The flow controlling parameters effects on subjective profiles are discussed in detail. Findings: The result shows that velocity field is reduced for magnetic parameter. Heat transfer is increased with enhanced Dufour number and Biot number. Furthermore, concentration profile is reduced with larger chemical reaction parameter. The motile microorganisms profile is reduced with larger Peclet number. The Local Nusselt number is declines via variation in porosity parameter and Dufour number.
