摘要

对热传递、污染积累和风位预测的更大、更精确的小气候模型的需求增加,给风洞研究人员以及使用计算流体动力学建模的研究人员带来了新的挑战。也就是说,问题是如何在不影响潜在关键细节的情况下,以低成本和快速的方式生成几何上准确和最新的模型。这是一个重要和日益严重的问题,因为越来越倾向于使用这种模式作为城市地区规划许可和长期政策决定的基础。本文回顾了微气候模型(物理模型和数值模型)的规模和细节水平的最新演变,并解释了在虚拟城市模型创建中应用传统采用的现有技术的困难。最后,本文概述了最近在几何创建和微气候模型数量方面的创新,通过使用航空激光扫描数据来克服现有文献记载的缺陷,即在所调查的模型中缺乏建筑细节。

Review of Strategies for the Geometric Creation and Population of Urban Microclimate Models
Heightened demand for larger and more accurate microclimate models for heat transfer, pollution accumulation, and wind level prediction has posed new challenges for researchers working in wind tunnels, as well as those employing computational fluid dynamics modeling. Namely, the problem is how to generate geometrically accurate and up to date models inexpensively and quickly without compromising potentially critical details. The problem is an important and growing one, as there is an increased tendency to use such models as the basis for planning permission and long-term policy decisions in urban areas. This review paper traces the recent evolution in the size and detail-level of microclimate models (both physical and numerical) and explains the difficulties of applying the existing technology traditionally adopted in virtual city model creation. Finally, the paper provides an overview of recent innovations in the geometric creation and population of microclimate models to overcome existing documented deficiencies in an absence of architectural detailing in the investigated models through use of aerial laser scanning data.
