扰流子结构对管内换热影响的三维数值研究
摘要
在空气流经管内换热器时
为获得较好的传热强化效果
本文分别采用四种不同结构的扰流子
在入口雷诺数Re从12 000到28 000的变化范围内进行三维数值模拟.经对比分析发现
扰流子的结构对换热效果和流动阻力均有较大影响
在实际工作中应综合考虑这两个因素的影响
选择最优方案.
Abstract
To obtain higher heat-transfer effciency when air flows through heat-exchange tubes
we performed 3-dimentional digital simulation with Reynolds number ranging from 12000 to 28000.The results show that the structure of the turbulator has big influence on both heat-transfer effciency and flow resistance.In practice
we should take into account both effects to choose the best solution.
