ABSTRACT Increasing attention is being paid to the study of heat transfer properties non‐Newtonian fluids as a result their growing use in many industrial and manufacturing processes. Micropolar have garnered lot interest for potential uses because distinctive microstructures. Both viscoelastic microstructural characteristics fluid make it mimic several polymers. Motivated by magnetic polymer coating dynamics operations, this article, thermoconvective nonlinear, steady‐state boundary layer flow an incompressible third‐grade micropolar from isothermal sphere with field thermal radiation investigated theoretically numerically. The model incorporates microelement gyratory (rotating) motions accurately simulates complex polymeric suspensions. An accurate implicit finite‐difference Keller‐Box method second order used solve numerically modified nondimensional conservation equations under physically suitable conditions. Verification code conducted using previous special cases literature. impacts parameters, that is, parameter ( ϕ ), material parameters ε 1 , 2 Biot number γ R Prandtl Pr M V Eringen vortex viscosity K dimensionless tangential coordinate ξ ) on linear (translational) velocity, angular temperature distributions are computed depicted graphically. Additionally, selected skin friction, wall couple stress (wall velocity gradient), Nusselt rate) also examined. As increases, accelerates farther away surface while decelerating close it. oscillatory response microrotation (angular) indicates reverse spin microelements. coupling (i.e., ratio Newtonian dynamic viscosity) causes accelerate decreasing closer Skin friction both increased, local depleted higher values parameter. With elevation (), there marked increase whereas (sphere gradient) depleted. There significant depletion rate (Nusselt number) increasing first exhibit considerable elevation. reduced. interaction parameter, significantly damped, enhanced (further surface) elevated substantially, thickness polymer. current simulations relevant high‐temperature processing electromagnetic polymers curved bodies.
