Simulation study of flow and heat transfer in a thermosyphon

By establishing a mathematical model in the thermosyphon system, the numerical simulation method is used for the temperature field, flow field distribution in heat pipe simulated calculation in recent years. In this article, we combine the thermosyphon engineering actuality, build up the Nusselt model, write the visual program with the VB code, and make use of the computer to carry on imitating the calculation. Meanwhile, the calculation predicted temperature profile in the thermosyphon was compared with experimental measurements and a good agreement was observed. Through the research, it can provide theoretical basis for the optimization of heat pipe model in the future.
