ABSTRACT

A three-dimensional two-fluid model for two-phase flow across tube or rod bundles is presented. The porous media concept is applied in model statement. Closure laws for interfacial mass, momentum and energy transfer, bundle flow resistance and heat transfer are presented. New correlations for the interfacial drag force are proposed. Developed model is suitable for the simulation and analyses of complex multidimensional thermal-hydraulics of nuclear fuel rod bundles or shell-and-tube heat exchangers with vapour generation within a tube bundle on the shell side.
