Mathematical modeling of the processes of heat transfer and hydrodynamics in a closed two-phase thermosyphon is carried out in a wide range of key parameters. The mathematical model is based on the laws of conservation of mass, momentum, and energy in dimensionless variables of stream function-vorticity vector-temperature. The influence of the Rayleigh number and the dimensionless time on the local and integral thermal hydrodynamic characteristics is estimated.
