摘要
基于κ-ε模型,分析了开口空腔系统内的热分层及流动特性,构建了几何模型,并应用Simple算法模拟分析了稳态条件下的热分层流动。数值研究表明,带隔板的空腔在不同理查逊数Ri下,隔板高度和间距等几何结构的变化对热分层特性影响显著。
The κ-ε turbulence model is applied to analyze the performance of the thermal stratification and flow structure for open cavity system.In this study,a geometric model is built and simulations with SIMPLE algorithm are used to investigate the thermal stratified flow under the steady condition.The results show that under the different Ri number,geometrical structure such as the height of diaphragm plates and their spacing,has remarkably impacted on the features of thermal stratification.
