In addition to the previously created hydrodynamics model, a mathematical model describing the heat transfer parameters of two-phase flow is constructed. Particular role of longitudinal convection in the heat transport is shown. The experimental studies confirmed a microchannel heat pipe operability with a two-phase flow in a circulating mode. A circulating two-phase Taylor flow in microchannel was considered to be more efficient for overall heat transfer in a heat pipe compared to the pulsating (oscillating) heat pipe. The advantages of circulating two-phase Taylor flow related to the pulsating heat pipes are discussed on the proposed mathematical model basis. The conditions of experimental proof of the proposed mathematical model were elaborated.
