摘　　要：简要介绍了风工程的3种研究方法及各自的优缺点,展示了计算流体动力学(CFD)在参数分析和足尺研究中的优越性,讨论了CFD中数值分析的相关问题和引入湍流模型的必要性,CFD对流场平均特性的描述已达到实用化程度,而脉动风载效应和风-结构相互作用问题还有待进一步研究.结合几个工程实际问题,阐述了CFD在建筑规划、防火、采暖、通风及结构领域的应用前景.Three research methods of building wind engineering and their characteristics are briefly introduced, and the advantage of applying Computational Fluid Dynamics (CFD) in parametric analysis and full-scale analysis is demonstrated. The related issues and the necessity of adopting turbulent model in CFD numerical simulation are discussed. The mean simulation results in fluid field can now be practically used, but further efforts are needed in the fields of wind-induced fluctuating response and wind-structure interaction. Several practical examples are taken to present the application future of CFD in architectural planning, fireproofing, heating, ventilation and structure.
