ABSTRACT
The experiment using porous heat pipe model with internal heat generation has been done to study the heat transfer characteristic on the porous material. Heat pipe model comprises a quartz tube with 300 mm length, 20 mm inner diameter and 3.5 mm thickness. Porous media were simulated using small steel balls. Working fluid which is used are water, propanol, and octane. Internal heat generation was simulated using high frequency induction. The experiment results showed that if boils have not occurred, heat transfer occurred by conduction process. Using the higher power, two phase flows will occur so that the heat transfer coefficient will increase.
