Computational fluid dynamics (CFD) analysis has been carried out to predict the overall temperature distribution of twophase thermosiphon, considered in the present study, and applied to experimental results under steady state conditions for three different heat inputs and two different working fluids with 50% filling ratio. In a thermosiph on or wickless heat pipe, the high heat transfer rate is due to the latent heat of evaporation and latent heat of condensation. The heat transfer coefficient (HTC) increases with the increase of the heat input. Results show that using pure fluid is more effective mixture. Comparison between results of the present work and a theoretical correlation of other researchers shows a good agreement, especially in the case of pure fluid. The predicted temperatures when using theoretical (CFD)are good with that of experimental results.
