Performance of an Inclined Tube of Open Thermosiphon - an Experimental Study

摘要

In this paper, rate of thermally induced flow and heat transfer in an inclined tube of open thermosiphon has been experimentally obtained under uniform heat flux conditions. The test section was a copper tube of 0.022 m internal diameter uniformly heated over a length of 2.13 m. Effects of heat flux and tube inclinations on heat transfer coefficient of water along the test section, were studied to evaluate the performance of an open -loop, inclined tube thermosiphon experimentally. The data have been presented graphically and discussed. Correlations for predicting the average heat transfer coefficient and mass flow rate are proposed.
