FUNDAMENTAL STUDIES OF FLUID FLOW AND HEAT TRANSFER IN FUEL ELEMENT GEOMETRIES I. Analysis of fluid flow and heat transfer in a triangular array of parallel heat generating rods

摘要

The purpose of the study presented in this report is to evaluate theoretically the magnitude of several hydrodynamic and thermal para-meters at various positions in the cross-section of a rod cluster. In order to avoid the necessity of taking into account the interactions be¬tween adjacent subchannels, the analysis is applied to a regular infinite array of rods with identical heat generation. The geometrical configu¬ration considered is the triangular pattern of rods.
