RESEARCH ON RESISTANCE CHARACTERISTIC IN BLANKET ASSEMBLY OF CHINA EXPERIMENTAL FAST REACTOR BY EXPERIMENT AND NUMERICAL SIMULATION

摘要

Experiment investigation and numerical calculation were carried out on frictional resistance characteristics of single-phase flow for China Experiment Fast Reactor(CEFR) blanket assembly.By using the CFD analysis ,me suitable size of Labyrinth throttling at the base pin to meet the requirements of design pressure drop were selected Then resistance characteristic experiment were carried on with the suitable size. It is show that numerical results agrees well with experiment results.The flow field was greatly affected by the labyrinth slructure of the throttling element in CEFR blanket assembly and resistance are mainly fouces on the CEFR's Labyrinth throttling at the base pin. It is show that using this method can effectively reduce experiment times, shorten research time and reduce the cost..
