Numerical Simulation of Heat Transfer in a Closed Two-Phase Thermosiphon

摘要

This paper presents the results of mathematical modelling of three-dimensional heat transfer in a closed two-phase thermosyphon taking into account phase transitions. Three-dimensional conduction equation was solved by means of the finite difference method (FDM). Locally one-dimensional scheme of Samarskiy was used to approximate the differential equations. The effect of the thermosyphon height and temperature of its bottom lid on the temperature difference in the vapor section was shown.
