Film Flow of the Heat-Transfer Agent in a Closed Thermosyphon

  • HEAT TRANSFER IN PHASE TRANSFORMATIONS

Journal of Engineering Physics and Thermophysics Aims and scope

Simulation of the influence of the parameters of film flow of the heat-transfer agent under gravity on the operation of a closed thermosyphon has been performed. It has been shown that in the stationary regime, the film thickness is under 100 μm. The main factors governing the efficiency of the thermosyphon are the power of the heat source, the area of the condenser, and also the viscosity and thermal conductivity of a liquid heat-transfer agent. The stability of film flow to a short-duration increase in the heat-source power has been considered.
