Abstract: 

This paper shows the effect of shear stress of liquid-vapor interface with and without mass transfer on thermal performance of a thermosyphon by the integral method. In this analysis, governing equation solved for laminar flow to find velocity profile, thickness of liquid film as well as heat transfer coefficient. In this study, a thermosyphon with 30.5cm length and 2.42cm inner diameter is analyzed. Methanol is used as a working fluid at saturated temperature of 63oC. Results show that the shear stress of liquid-vapor interface decreases the rate of heat transfer.
