Heat transfer is one of the most important aspects in designing and maintaining the thermal system. This moving-from-high-to-low temperature phenomenon really affects the condition of a system. One of the challenges in research of heat transfer that has not been done is finding the correlation between Rayleigh number and Nusselt number for convection heat transfer on the upper surface of a hot inclined plate or lower surface of the cold inclined plate. In this final project, the task is to find the correlation between the Rayleigh number and Nusselt number for the convection heat transfer case. CFD (Computational Fluid Dynamics) program is used to simulate the heat transfer and calculate the total heat transfer flux on the surface. After finding the total heat transfer flux, Nusselt number could be calculated and we will find the correlation between the Nusselt number and the Rayleigh number of the system using jacobian matrix. Based on the simulation and calculation that has been done, it can be concluded that the correlation for two-dimension between Rayleigh number and Nusselt number is ????????????= ????. ???????????????? where variable C = 0.868 and m = 0.214 for the angle of 30 m = 0.202 for the angle of 45o, and C = 1.044 and m = 0.192 for the angle of 60 dimension case, variable C = 0.351 and m = 0.197 for the angle of 30oo, C = 0.971 and o. For three , C = 0.414 and m = 0.198 for the angle of 45o , and C = 0.485 and m = 0.183 for the angle of 60. For other angle variation, interpolation can be applied to determine the variable C and m for both cases.
