摘要
文中基于计算流体力学(CFD)数值模拟,建立了一种室内外气流耦合模型,研究了翻板遮阳对多层建筑室内外风环境的影响。通过对比3种遮阳工况下的流线分布、风速云图和室内通风量大小,分析遮阳翻板的安装位置和前排建筑遮挡对室内风速分布和通风量的影响。结果表明:在迎风遮阳工况下,由于前排建筑的遮蔽,后排建筑的室内通风量会显著下降;在背风遮阳工况下,后排建筑的室内通风量下降得最为明显;相比无遮阳,迎风遮阳会降低前排建筑的室内通风量,而背风遮阳则影响较小。
Based on computational fluid dynamics(CFD)numerical simulations,this paper establishes a coupled indoor-outdoor airflow model to study the impact of louver shading on the wind environment inside and outside multi-story buildings.By comparing streamline distributions,wind speed contour maps,and indoor ventilation rates under three shading conditions,the influence of the installation position of shading louvers and the shading effect of front-row buildings on indoor wind speed distribution and ventilation rates were analyzed.The results indicate that,under the windward shading condition,due to the shielding effect of the front-row buildings,the indoor ventilation rate of the rear-row buildings decreases significantly;under the leeward shading condition,the decrement in the indoor ventilation rate of the rear-row buildings is the most;compared to no shading,windward shading reduces the indoor ventilation rate of the front-row buildings,while leeward shading has a relatively minor impact.
