摘要：
A one-dimensional model of two-phase flow and heat transfer has been presented for a closed thermosyphon loop with minichannels heated from the vertical side and cooled from the horizontal one. The model is based on mass, momentum, and energy balances in an evaporator, rising tube, condenser and a falling tube. A separated two-phase flow model is used in calculations. The effect of geometrical parameters of the loop on the mass flux rate in a steady state has been numerically examined. A numerical analysis of the heat transfer coefficient in a flow boiling and condensation has been done.
