Abstract

Two approaches for estimating heat flow from a wall pulsation tube to the working fluid were considered. The analysis of existing empirical dependences describing the coefficient of hydraulic resistance of the regenerator conducted. The algorithms for calculating the mass flows were modified by through the valves and heat flow in the channels on the basis of a model on structural and modular approach. The equations for calculating heat transfer coefficients in the tube and recommendations for determining the hydraulic resistance in the low-temperature regenerators' coolers with the pulsating tube are obtained. The differences in values of calculated and experimental integral characteristics not exceed 25 %.
