New generalizing relations are derived to calculate effective turbulent transfer coefficients used to close a system of equations describing thermal and hydraulic processes in such rod bundles. The physical phenomena that characterize the specific features of heat and mass transfer for different types of unsteadiness are considered. The developed empirical method for closing a system of equations is based on both the hypothesis for local similarity of transfer and mathematical formalism in solving the problems. %8 2001-12-01
