Human activity is known to leave significant effects on indoor airflow patterns. These patterns are carefully designed for many facilities such as cleanrooms, pharmaceutical settings, and healthcare environments, where human‐induced wakes contribute to the transport of contaminants. Therefore, the knowledge about these wakes as it relates to indoor air quality is critical. As a result, a series of experiments were conducted in a controlled chamber to study the three‐dimensional effects of true human walking on airflow. Experiments were designed to capture the effect of human walking under three different flow conditions, and for two different walking schemes. The results show that the effect of walking on the airflow is not negligible and can sustain up to 10 seconds after the moving body has passed. Walking on a straight line creates significant change in the velocity normal to the walking path and vertical to the plane of walking movement. These changes were detectable till 1.0 m away from the walking track. Also, the similarity between airflow patterns of walking once and twice illustrated a promising opportunity of predicting the flow patterns of random walk from a set of base cases.

人体运动对室内气流模式影响的三维分析

众所周知，人类活动会对室内气流模式产生重大影响。这些模式是为许多设施精心设计的，例如洁净室、制药环境和医疗保健环境，在这些环境中，人为引起的尾流有助于污染物的传输。因此，了解这些与室内空气质量相关的尾流是至关重要的。因此，在受控室中进行了一系列实验，以研究真实人类行走对气流的三维影响。实验旨在捕捉人类在三种不同流量条件下以及两种不同步行方案下行走的效果。结果表明，行走对气流的影响不可忽视，在移动的物体经过后可以持续长达 10 秒。沿直线行走会使垂直于行走路径和垂直于行走运动平面的速度发生显着变化。这些变化在距离步行道 1.0 m 之前都可以检测到。此外，步行一次和两次的气流模式之间的相似性说明了从一组基本案例预测随机步行的流动模式的有希望的机会。
