计算流体动力学（CFD）越来越多地应用于实际高层建筑周围风环境的预测。尽管其应用日益广泛，但预测精度以及许多可能影响模拟结果的因素尚未被完全理解。为了阐明模糊之处，并为风环境的CFD预测制定指南，日本建筑学会组织了一个工作组。该小组进行了如下各种比较研究：第一阶段：两种类型的单体高层建筑周围的流场；第二阶段：位于城市中的一座高层建筑周围的流场；最后阶段：实际城区中两种类型的建筑群周围的流场。本文描述了该工作组的一些调查结果，并讨论了各种计算条件对CFD结果的影响，以及CFD在风环境预测中的现状和问题。（c）2007爱思唯尔有限公司。保留所有权利。
CFD (computational fluid dynamics) is being increasingly applied to the prediction of the wind environment around actual high-rise buildings. Despite this increasing use, the prediction accuracy and many factors that might affect simulation results are not yet thoroughly understood. In order to clarify ambiguities and make a guideline for CFD prediction of the wind environment, a working group was organized by the Architectural Institute of Japan. This group has carried out various comparative studies as follows.First stage: flow fields around two types of single high-rise buildings.Second stage: Flow field around a high-rise building located in a city.Last stage: Flow fields around two types of Building Complexes in actual urban areas.This paper describes some of the results of the investigation by the working group, and discusses the influences of various calculation conditions on CFD results, and also on the present status and the problems in CFD prediction of the wind environment.
