摘要
将多孔蓄热墙应用于玻璃屋中,并建立了描述多孔墙蓄热作用的能量双方程模型。采用k-ε紊流模型和饱和多孔介质Brinkman-Forchheimer Extended Darcy模型,对玻璃屋-多孔蓄热墙内耦合传热与流动特性进行研究。结果表明:玻璃屋入口流速对室内及多孔墙内空气的温度场与流场有较大的影响。因此,针对一定结构的玻璃屋,合理地设计风机,控制风机的运行工况,将有利于合理控制室内的环境。
The porous heat-storage wall was applied in glass house. The new energy double equation model for saturated porous medium was given to describe the heat-storage effect of porous wall. Based on the k-ε turbulent model and Brinkman-Forchheimer Extended Darcy model, the coupled heat transfer and flow performance were studied. The result shows that the inlet velocity has significant influence on the temperature field and flow field in glass house. Therefore, reasonable design and good operation situation of the fan will be conducive to control of indoor environment.
