摘要
采用零方程模型和3点动量风口模型,应用计算流体力学软件PHOENICS模拟了某候机厅空调气流组织方案的速度场和温度场。模拟结果显示,原方案工作区断面温度达不到设计要求,风速超出规范要求,改进方案保持总风量不变,增加了送风口数量,其温度场和速度场都能满足规范要求。
Simulates the air distribution in an air conditioned airport hall by PHOENICS using zero equation turbulent model and three point momentum draught model. As a result, the air temperature distribution can not meet the design demand, and the air velocity exceeds the demand value in the design code with original scheme, and with the improved scheme of the same air flow and more air outlets, the distributions of temperature and velocity can meet code requirements.
