Quantitative study of air layer under multi-opening air ventilation clothing

In order to study the influence of clothing with different opening position and wind speeds on the volume, thickness and distribution of air layer under an air ventilation clothing, three-dimensional scanning method was adopted to obtain geometric models of human body and clothing. The model was then processed by reverse engineering software, Geomagic Control, to analyze the difference in thickness and volume of air layer and obtain the distribution regularities of air layer under different conditions. The results show that the influence of wind speed on the average air layer thickness is more obvious than that of the opening mode. The wind speeds of the fans have a significant effect on the overall and local air layer thickness. The higher is the wind speed, the thicker is the air layer in body part, and more evenly distributed is the air layer. From the two-dimensional comparison of the air layer in the chest and waist areas, it can be seen that the thickness of the air layer in the chest does not change significantly with the changes of the wind speed and the opening, while the air layer in the waist is affected significantly.
