ABSTRACT The current investigation objective is to employ a semianalytical method to observe the micropolar fluid flow dynamics in the vicinity of a stretched surface through a chemical reaction of medium that is nonlinear, nonlinear radiation, heat dissipation, variable viscosity, and modified Fourier heat flux effects influenced by convective boundary conditions. The Chebyshev collocation technique is employed to solve the dimensionless ordinary differential equations, which are converted from dimensional partial differential equations using similarity transformations. The research also examines the performances of velocity, temperature, microrotation, and concentration fields due to the effects of various flow‐influencing supervisory parameters within the boundary layer by representing these findings through graphical diagrams. The comparison of the couple‐stress, friction factor, and mass and thermal rates has been done by the computed numerical data presented in the table. The final results show that velocity profiles decreased by increasing the microgyration factor and material parameter, whereas microrotation exhibited the opposite trend. An upsurge in the first‐order slip parameter leads to fluid velocity and microrotation depreciation. The potency of the magnetic field impelled to deflate the fluid moment, but the increased porosity parameter intensified fluid velocity. The thermodiffusion effect leads to an expansion concentration field, but the chemical reaction and Schmidt number have opposite impacts. The magnetic and temperature ratio parameters are driven to intensify the skin friction and couple stress, but thermal relaxation and radiation parameters have evidenced opposite effects.
