EXPERIMENTAL AND THEORETICAL-STUDIES INTO TRANSVERSE TURBULENT TRANSFER OF MOMENTUM AND ENERGY IN COMPLEX-SHAPED CHANNELS

The data are given on transverse interchannel exchange of momentum and energy in rod assemblies under conditions of single-phase flow of a h eat transfer agent. They were derived as a result of processing of dat a of experimental hydrodynamic studies in deformed lattices according to an ingenious procedure developed by the authors, and of thermal stu dies using the method of heat wake in regular and deformed lattices of rods. The obtained data are compared to the results of other research ers. A physical model of the process of transverse turbulent exchange in rod-type systems is suggested and calculation formulas are derived for the exchange coefficients, which are compared with experiment. The data on interchannel exchange in two-phase flows are analyzed.
