Bioconvection Flow in the Existence of MHD Carreau Nanofluid With Cattaneo–Christov Model

ABSTRACT This study explores the analysis of the magnetohydrodynamic stagnation point flow of the Cattaneo–Christov thermal flux model of Carreau nanofluid over a stretched sheet incorporating gyrotactic microorganisms and Joule heating. Moreover, integrating the influences of activation energy, chemical reactions, heat source, Brownian motion, and thermophoresis provides the distinctiveness of this investigation. Numerical outcomes are attained using a Runge–Kutta‐based shooting technique implemented via the MATLAB BVP5C approach. The influences of several dimensionless parameters on velocity, thermal, and concentration profiles are represented graphically. Notable findings indicate that the thermal distribution is enhanced for augmenting the heat source and thermal radiation.
