基于SANA实验的三维热工分析程序计算验证
Computational verification of 3D thermal analysis program based on SANA experiment
摘要
Abstract
To reduce the high number of errors in traditional two-dimensional(2D)thermal-hydraulic analysis pro-grams when handling asymmetric geometries and axially nonuniform heating in the pebble bed high-temperature gas-cooled reactor(HTGR),a more accurate and detailed thermal-hydraulic analysis program called DAYU3D was de-veloped based on the 2D thermal-hydraulic analysis software DAYU2D.A 3D heat conduction and convection mod-el suitable for a spherical bed HTGR was established in DAYU3D.Subsequently,symmetric and asymmetric heat-ing conditions from the SANA benchmark experiments were simulated and compared with experimental results using this program.The calculation results revealed that compared with the 2D program,DAYU3D provides better agree-ment with the experimental results for the 3D asymmetric heating conditions of the SANA experiments than the 2D program,thus making it more suitable for the 3D thermal-hydraulic analysis of the pebble bed HTGR′s thermal characteristics.关键词
