Abstract

Abstract

Experimental study on flow resistance coefficient of tight lattice fuel assemblies was per-formed,and a new correlation was proposed.Comparison between new correlation and typical Rehme corre-lation shows the latter correlation is not suitable for the test section.CFD study with SST model was per-formed to simulate experiments and analyze flow field,pressure field and flow resistance coefficient.The re-sults show that CFD method can be a reference for the prediction of single phase flow resistance of wires wrapped tight lattice rods bundle.
