This research is about the getting to know of the natural convective of heat transfer inside a solar collector with inclination. The same type of solar collector with different shaped absorber are compared. One has a wavy absorber and another has a flat absorber. the cover and walls of the solar collector are assumed as isothermal boundary condition for the simulation. The parameters taken into consideration are the Rayleigh number, inclination angle, wave length, and aspect ratio. Results are shown through the streamlines from the simulation, isotherms produced, and the local and mean Nusselt number. From the results, it can be seen that the shape of absorber effect the flow and thermal fields. This increases the rate of that transfer in the wavy absorber.
