Examining the behavior of MHD micropolar fluid over curved stretching surface based on the modified Fourier law

The present study describes Magnetohydrodynamic micropolar fluid over a curved stretching surface, based on Cattaneo-Christov theory of heat diffusion. In this paper, the new heat model with the relaxation time is employed in this paper, instead of classical theory of heat flux presented by Fourier. The curvilinear coordinates are used to model the governing equations. The nonlinear Partial Differential Equations (PDEs) are changed into Ordinary Differential Equations (ODEs) through a proper transformation process. The nonlinear ODEs are solved with the help of OHAM by using BVPh2. The variation of several parameters is indicated and examined graphically. We have observed that the pressure and velocity rises by increasing the radius of curvature. The thermal relaxation time and Prandtl number reduces the temperature profile.
