ABSTRACT
Based on the analysis of two-phase flow mechanism, transition from bubbly flow to slug flow and from slug flow to churm flow in a thermosyphon using LiBr- H2O as working fluld have been modeled in this paper. Experiment has been setup to validate the theoretical model and to evaluate the pumping characteristics of the thermosyphon. The variations of the generator pressure, flow resistance and driving head with heat input are presented graphically. Results indicate that strong solution and vapor flow rates increase with heat input and so dose the pumping ratio. In addition, the suitable heat input range corresponding to a certain thermosyphon tube diameter range was determined. These results can be used to design thermosyphons using LiBr-H2O as working fluid.
