The current work examines the behaviour of micropolar Carreau nanofluid flow past an infinite vertical plate with nonlinear thermal radiation. Magnetic field, heat source/sink, viscous dissipation, internal and Joule heating effects are considered. The governing equations are reframed and expressed in the non-dimensional form with appropriate dimensionless quantities to analyse the model. The nonlinear non-dimensional governing equations are solved numerically using finite difference approximation to acquire the solutions. Impact of involving flow controlling parameters on fluid flow, heat and mass transport characteristics are discussed and presented via tables and graphical illustrations. Our outcomes figured out that the fluid motion and angular velocity declines with greater magnetic parameter values, and reverse trend is observed for micropolar constant. Further, computational results depict that thermal distribution is a rising function of radiation parameter and high thermal performance is observed; that is, 10.45% more temperature distribution is noticed in presence of nonlinear thermal radiation.
