FILM FLOW OF THE HEAT-TRANSFER AGENT IN A CLOSED THERMOSYPHON

Simulation of the infl uence of the parameters of fi lm fl ow 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 fi lm thickness is under 100 μm. The main factors governing the effi ciency 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 fi lm fl ow to a short-duration increase in the heat-source power has been considered.
