Thermal features of Darcy-Forchheimer on a micropolar fluid flow over a curved stretching surface with homogenous-heterogeneous reactions

Abstract

The main focus of contemporary study is to explore the Darcy magnetized flow of a micropolar second-grade fluid by consideration of homogeneous-heterogeneous reactions over a curved stretching surface. The thermal aspects of the fluid flow are analyzed with the inclusion of joule heating and thermal radiation effects. Moreover, magnetic field is imposed normal to the surface and thermal stratification condition is considered on the boundary of surface. An appropriate transformation is used to convert the flow model into a set of ordinary differential equations, which are nonlinear in the nature. The numerical solutions of this nonlinear system of equations are obtained using the bvp4c technique on MATLAB. The velocity, temperature, concentration, and micro-rotation distribution variation for various parameter is shown graphically and with numerical data. The main finding in the current problem to see that that greater estimation of micropolar parameter improves the angular velocity of the fluid, whereas linear velocity of fluid declines for larger values of magnetic parameter because of the resistance effect take place due to magnetized flow. Furthermore, it seems that curvature parameter produces the improvement in the linear and angular velocity of the fluid.
