摘  要:
采用CFD(Computational fluid dynamics)方法对南疆地区的羊舍内自然通风下的室内环境进行数值模拟。模拟时对整个计算区域采用六面体网格进行划分,对羊舍天窗和北窗附近区域的网格进行加密处理,生成的网格数约为453 360个。羊舍CFD数值模拟以室内外空气作为研究对象,外界气象条件、羊舍外维护结构和室内地面等作为边界条件处理。对冬季南疆地区羊舍北窗开启和关闭两种情况下室内的速度场、温度场进行数值模拟。根据数值模拟的结果表明在白天可以开启北窗进行通风。

摘  要:
Simulate a naturally ventilated sheep house in the south of Xinjiang with computational fluid dynamics(CFD) method and the governing equations,grid generation and boundary conditions of the CFD method were introduced. The air temperature distribution inside the sheep house was simulated when the windows of north wall were open and close.The effect of ventilation when both the side and roof windows were open was better.
