Numerical Analysis of Liquid Metal Cooled Rod Assembly

A benchmark experiment on heat transfer in a model subassembly of a liquid metal cooled reactor was exercised as a standard problem in a working group meeting on the hydrodynamics and heat transfer organized and sponsored by the International Association of Hydraulics Research. The standard problem aims to analyze thermal and hydraulic characteristics in the model pin bundle under nonuniform geometrical and thermal conditions in square array of pins. A spacer grid exists in the pin bundle with variable heat production zones. The problem also intends to estimate the reliability and accuracy of codes used for thermal hydraulic analysis
