本文综述了建筑物周围积雪的计算流体力学(CFD)建模的现状，并讨论了综述结果，以期对未来的应用有更深入的了解。首先，通过回顾前人的研究，对建筑物周围积雪的CFD模拟的研究成果进行了综述。简要概述了模型开发的历史。然后，从实际设计的应用、气象影响的考虑和屋面积雪的预测等几个方面介绍了最近的应用实例。最后，从工程的角度提出了仍然存在的发展问题和新的挑战。论证了进一步开发模型、验证数据库、最佳实用指南和使用CFD结果进行高级分析的必要性。显然，正如本综述所确立的那样，CFD具有相当大的潜力。然而，要恰当地使用它，必须在建模理论和实现上给予足够的重视。由于雪崩是一种高度复杂的现象，我们不应过度依赖数值模拟。在研究的各个方面，使用来自实际现象的数据是很重要的。
This paper reviews the current status of computational fluid dynamics (CFD) modeling of snowdrift around buildings and discusses the review findings to give insight into future applications. First, an overview of past achievements in CFD simulations of snowdrift around buildings is provided by reviewing previous research. The history of model development is briefly outlined. Next, recent application examples are presented with respect to several topics, i.e., the application to practical design, consideration of meteorological influences and prediction of roof snow. Finally, the remaining development issues and new challenges are presented from an engineering viewpoint. Necessities of further model development, validation database, best practical guidelines and advanced analysis using CFD results are demonstrated. Clearly, CFD has considerable potential, as established in this review. However, to use it appropriately, sufficient attention should be paid to modeling theory and implementation. Because snowdrift is a highly complex phenomenon, we should not excessively rely on numerical simulation. It is important to use data from actual phenomena for all aspects of study.
