So far, this research group has conducted a wind tunnel experiment to measure the spread rate using a small fan to measure the effect of wind on the fire spread rate. However, since the problem remained in the air flow condition, we made a portable multiple wind tunnel device that can be transported and inexpensive.
In this study, we emphasized durability and transportability to improve the problems of prototypes and made a portable multiple wind tunnel using 3D CAD and 3D printer. By using a 3D printer, the contraction body, rectification body, and diffusion body became easily removable wind tunnel.
In the future, the shape of the contraction body will be improved, and the increase of the wind speed, the uniformity of the wind speed distribution, and the evaluation of the turbulence will be carried out.
