中文摘要	以高温堆热气联箱为研究对象,在实验研究的基础上,采用流体力学计算程序CFX5对热气联箱和热气导管内部流场进行了数值模拟,以获得热气联箱和热气导管内的速度场、压力场和温度场,为高温堆热气联箱的设计和实验研究提供参考。数值计算结果表明:热气联箱内气流发生剧烈搅混,加速了不同温度气流间的热传递,有利于高温和低温气流间的温度混合。但存在肋片的区域没有发生剧烈的气流搅混,不利于气流间的热传递。热气导管内温度混合率随其长度的增加逐渐增大,热气导管长度2.5m以上时,温度混合率达到99%以上。; This study used the Computational Fluid Dynamics(CFD) program CFX5 to calculate the flow in the hot gas chamber and the hot gas duct in high temperature reactor,on the basis of the experimental research.The calculated results including velocity flow field,pressure field and temperature field were ob-tained,which could be a reference for the design and experimental research of the hot gas chamber of the high temperature reactor.The numerical simulation results indicated that the gases in the hot gas chamber mixed intensively,which accelerated the heat transfer for the gases with different temperatures,and which was in favor of the temperature mixing for high temperature and low temperature gases.In the ribs area,the gas mixing is not so intensive,which had negative effect on the heat transfer between gases with different tem-peratures.The temperature mixing rate in the hot gas duct increased with the increase of the hot gas duct,and when the length of the hot gas duct was more than 2.5 m,the temperature mixing rate was above 99%.; 国家自然科学杰出青年基金项目50325620; 国家自然科学基金项目10372050资助
