空调房间中由于送风时存在温差,产生的浮升力对气流流动有影响,本文采用了三维紊流的 K-ε模型进行分析,并对其加入了浮升力的修正。在边壁上利用高雷诺数的 K-ε模型加壁面函数来处理边界条件,据此,编制了相应的计算机程序,并计算分析了一间典型宾馆客房的气流组织情况,其结果与实验相当吻合。
In the air-conditioned room, due to the temperature difference during the air supply, the buoyancy generated has an influence on the air flow. In this paper, a three-dimensional turbulent K-ε model is used for analysis, and a buoyancy lift correction is added. On the side wall, the boundary conditions are processed using the high Reynolds number K-ε model and the wall function. Based on this, the corresponding computer program is compiled, and the airflow organization of a typical hotel room is calculated and analyzed. The results are comparable to those of the experiment.
