Abstract
Here, mathematical modeling is performed for the nonlinear mixed convection in dissipative convective flow of micropolar fluid towards a stretched surface. Mixed convection occurs when both forced and natural convection mechanisms act together. Mixed convection problems are categorized by Grashof number. This is also addressed as situations where both buoyant and pressure forces interact. Slip condition is considered at the boundary for the velocity. Magnetohydrodynamics (MHD) fluid is considered. Novel features of nanofluids like Brownian motion and thermophoresis diffusions are further addressed. Convective condition is imposed at the stretched boundary. Concentration of material particles is discussed with activation energy. Nonlinear partial differential equations are converted into ordinary ones via appropriate similarity transformations. The velocity, temperature, concentration, skin friction, Nusselt number, and entropy generation are discussed numerically with the help of built‐in‐shooting method. Our obtained outcomes show that the velocity of material particles reduces against larger slip parameter and micropolar parameter. Temperature enhances for larger thermal Biot and Eckert numbers. Concentration of fluid particles is more versus solutal Biot number and activation energy parameter. Furthermore, entropy rate increases for higher values of micropolar fluid parameter and activation energy parameter while it declines against slip parameter.
