Convective Heat Transfer is the conduction process where it combines heat diffusion and advection which is heat transfer by bulk fluid flow. The boundary layer is a thin layer that runs along the edge of the solid boundary. This research investigated the mixed convection flow at the lowest stagnation point towards horizontal circular cylinder saturated in the porous region using the Brinkman model with constant wall temperature boundary condition. An appropriate similarity transformation is used to decrease the complexity of the equations. The effect of velocity and temperature profile on mixed convection and Brinkman parameters are calculated using BVP4C in Matlab. The purposes of the study are to transform partial differential equation to ordinary differential equation and to determine whether the Brinkman parameter and the mixed convection parameter affect the temperature and velocity. The result shows that the velocity profile appears to be decreasing as the Brinkman parameter value rises. Other than that, the finding also highlights the effect of the temperature profile, which appears to be increasing in correlation with the value of the Brinkman parameter which is also increasing. For the mixed convection parameter, when it is increased, the velocity profile increases but the temperature profile decreases. The results in the table are obtained by comparing with other research articles to confirm that they are accurate. These tables are crucial, as they may be used as a reference against which further accurate or approximate answers can be compared.
