Abstract
Sequel to the usefulness of exploration of Carreau fluid
flow for understanding the nature of the shear thinning
and thickening characteristics of industrial fluids and
polymer suspensions, nothing is known on the heat
transfer across the dynamics of Carreau fluid subject to
three kinds of stratification (i.e., thermal, concentration,
and diffusion of motile microorganisms). In this
article, the motion mentioned above when inclined
Lorentz force, haphazard motion of tiny particles,
thermophoresis, and motile gyrotactic microorganisms
are significant is presented, explored, and deliberated
upon. Similarity transformation variables were employed
to reduce the model from partial to ordinary
differential equations. The Runge–Kutta–Gill methodology
was used in conjunction with the shooting
method and MATLAB bvp4c to obtain the numerical
solution. It is worth concluding that thermal stratification
and wall heating/temperature ratio terms promote
heat transmission while increasing the size of the
Weissenberg number and the mixed convection
parameter lowers the skin friction coefficient. Furthermore,
it has been shown that when stresses grow,viscosity promotes the deformation of fluid components,
resulting in fluid velocity retardation
