چکیده :

In this study, the geyser boiling in a two-phased closed thermosyphon was investigated experimentally. Some parameters such as inclination angle (φ), filling ratio (FR) and aspect ratio (AR) and heat input (Q) and the coolant mass flow rate ( ) affect the geyser boiling in thermosyphon . A series of experiments were carried out to investigate the influence of the above parameters on the period and intensity of geyser boiling under the normal conditions. Two Copper pipes of 1000 mm length and 15mm and 25mm as inside diameter and methanol as the working fluid were employed. An experimental equation was offered to correlate the data for the period of geyser boiling. The results showed that the period of geyser boiling decreased by increasing the heat loud and aspect ratio and increased by increasing the filling ratio. The results were compared with the results found in the literature and a good agreement exists.
