风洞提供了一种有效的工具，可以快速获得与比例或全尺寸模型相关的流动数据。考虑到风洞无处不在的特性和实用性，风洞设计项目是一项相当普遍但又复杂的工作。因此，本文回顾了低速风洞设计的基本原理。讨论了研究目标和具体测量要求，以及指导隧道设计的各种空间、预算和功率约束。为最常见的风洞组件提供了设计指南，包括气流调节器、收缩器、试验段、扩散器、驱动器和其他可选组件。最后，简要总结了设施的表征过程，包括流动均匀性、湍流强度、背景噪声和振动水平。关键词：风洞；流体动力学;空气动力学;实验方法
Wind tunnels offer an effective tool to rapidly obtain data associated with flow over scaled or full-scale models. Given their ubiquitous nature and utility, a wind-tunnel design project is a fairly common yet complex exercise. We therefore review in this article the fundamentals of low-speed wind-tunnel design. The research goals and the specific measurement requirements are discussed, as well as the various space, budget, and power constraints that guide the tunnel design. Design guidelines are provided for the most common wind-tunnel components, including flow conditioners, contraction, test section, diffuser, drive, and other optional components. Finally, facility characterization procedures are briefly summarized, including flow uniformity, turbulence intensity, and background noise and vibration levels.
