双层幕墙热气流流体动力学热工模拟

 在强太阳热辐射条件下,双层幕墙强迫送风热气流（简称强化热气流）流量及热功率显著增加。建立三维流体动力学模型及边界条件,采用FLUENT软件对双层幕墙热气流及强化热气流进行热工模拟,求得双层幕墙在无遮阳、遮阳百叶全开、遮阳百叶封闭三种工况下的温度及速度分布图,解析强化热气流的成因。最后再通过实验验证。

Double Glass Curtain Wall Heat Flow Thermal Simulation of Fluid Dynamics

In the strong sun radiation condition, the heat flow and thermal efficiency of double glass curtain wall are significantly increased with the forced air flow (referred to as the strengthening heat flow). The three-dimensional hydrodynamic model and the boundary condition are established. Using software of FLUENT, the thermal simulation of airflow and strengthening heat flow are executed. Under three different conditions of open,closed and without shading louver, the temperature and velocity distribution diagram are drawn, and the cause of strengthening heat flow are analyzed. Finally, verification experiment are completed.
