Analysis of the Efficiency of Flow Accumulators of Phase Transition Heat

A condition for the most optimal characteristics of the accumulator is obtained by using a quasi-stationary one-dimensional model of heat transfer in flow heat accumulators. The concept of the efficiency coefficient of recuperative heat exchangers for estimating the phase transition accumulator is substantiated. Approaches of physical and mathematical modeling to obtain analytical relations used to calculate heat transfer processes in flow accumulators with phase transitions, characterized by the uneven temperature field in the direction of the coolant flow, are analyzed. The dependences obtained are applicable to calculate the initial and final stages of the phase transition process. The application of the dependences obtained for more accurate calculations is justified.
