Abstract

The air flow profile around a cylinder, covered with textile, was analyzed both theoretically and experimentally. A model was deduced, which describes the air flow through and underneath clothing that is covering a body part. In the air profile model presented here, the body part is represented by a cylinder. The model was validated by conducting pressure measurements around the cylinder, both with and without clothing. These pressure profiles were used to calculate the velocity profile around the cylinder, which was then compared to the theoretically predicted velocity profile. There is a good agreement between the measurements and the model. The model was also used to validate an empirical formula, which is used at present, that described the air velocity through the clothing as a function of the wind velocity. A correction factor for this formula is proposed. © 2006 American Institute of Chemical Engineers AIChE J, 2006

通过身体部位周围衣服的气流的理论和实验研究

本文从理论和实验两方面分析了织物覆盖圆筒的气流分布。推导出了一个模型，该模型描述了覆盖身体部位的衣服中空气的流动情况。在这里给出的空气廓线模型中，车身部分用圆柱体表示。该模型通过在圆柱体周围进行压力测量来验证，无论是否穿衣服。这些压力分布用于计算圆柱周围的速度分布，然后将其与理论预测的速度分布进行比较。测量结果和模型吻合得很好。该模型还用于验证目前使用的经验公式，该公式将穿过衣服的空气速度描述为风速的函数。提出了该公式的修正系数。©2006美国化学工程师学会，2006
