【摘要】 本文采用经过浮力项修正的高Re数k-ε双方程模型和壁面函数法、风口模型相结合的方法建立了空调房间内空气流动的三维紊流数学模型,并以一单间空调房间为研究对象,针对侧送侧回和侧送异回气流组织方式,应用FLUENT分别对夏季和冬季送风参数(送风速度、送风方向和送风温差)对室内空气速度场和温度场的影响进行了数值模拟,并通过分析研究了室内空气在不同送风参数下的速度和温度分布规律,从而为空调房间的实际运行提供指导性的结论。更多还原

【Abstract】 In this paper, a buoyancy-revised high Reynolds number k-ε turbulence model, wall function, and inlet model are used to establish a three-dimensional turbulence mathematical model of an air-conditioned room, and one air-conditioned room is taken as a research object. The air supply and return the same side, and the air supply side and return opposite side are aimed at, and FLUENT is used to simulate influence of air inlet parameters (air inlet velocity, air inlet direction, and the difference in temperature) in summer or in winter on indoor air velocity field and air temperature field. Moreover, laws of the air velocity and air temperature distribution inside the air-conditioned room with various air inlet parameters are studied. Consequently, instructional conclusions are provided for practical operation of an air-conditioned room.更多还原
