ALGEBRAIC STRESS MODEL FOR AXIAL FLOW IN A BARE ROD-BUNDLE.

Abstract

The problem of predicting transport properties for nomentum and heat across the boundaries of interconnected channels has been the subject of many investigations. The paper reports an attempt to describe the turbulent stresses by means of an Algebraic stress Model for turbulence. Relative turbulent kinetic energy distribution in all three directions are presented and compared with experiments in a square lattice. The directional dependence of transport terms are obtained via a model for the Reynolds Stresses.
