计算流体力学在城市规划设计中的应用研究

Application of Computational Fluid Dynamics in the Field of Construction Planning

应用CFD方法对规划的建筑群进行小气候数值模拟 ,预测规划方案使楼宇、街区小气候发生的改变 ,以趋利避害 ,是一种经济、有效的研究手段。文中试图探讨CFD在规划设计中应用的具体实施方法。通过对个案的研究 ,揭示CFD在规划设计中所能扮演的角色。CFD可以通过在规划初始阶段的介入 ,为规划设计人员提供指导性参考 ,使规划更能体现以人为本的设计思想。

Computational Fluid Dynamics (CFD) is used in the construction planning stage. Wind field in the planned buildings was analyzed by CFD. By analyzing the computed wind field, the pro side of the planning design can be emphasized and the con side of the design can be modified. The CFD approach is an economical and efficient way to improve planning quality. In the case study of an urban square planning, a detailed wind field is analyzed by CFD, and the result supports the planning design.
