Turbulent mixing in 19-rod assembly with nonequivalent elementary cells

Abstract

Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.

This paper present experimental results of turbulent mixing in 19 smooth and rough rods assembly with thermohydraulic nonequivalece of elementary cells and a pitch-to-diameter ratio s/d = 1.35 in a circular shell.
