Abstract

In this paper, mixed convection flow is considered with micropolar fluid in the presence of the magnetic field. In addition, the flow is defied with a non-linear stretching sheet through a porous medium. Non-uniform heat generation/absorption as well as chemical reaction are studied. The similarity transformation is used to change the governing equations. The Homotopy Analysis Method is used to solve the system of ODE. The impacts of several important parameters on velocity profiles, angular velocity profiles, temperature profiles and concentration profiles are represented graphically. With the help of tables, the coefficients of Skin friction, Nusselt number, and local Sherwood number are also anticipated and shown. When the new finding results were compared to earlier findings, they revealed a high-level agreement. The findings show that the velocity profile and angular velocity profiles are enhanced by thermal radiation parameter and material parameter. When Biot number and Eckert number are raised, the temperature profiles increase noticeably. Furthermore, when the chemical reaction parameter is raised, the concentration profile is reduced and it is improved as Soret number is increased. Heat transfer rate increased as thermal radiation parameter increased and decreased as Biot number decreased for both linear and non-linear stretching.
