Design and development of a low-cost open-type wind tunnel

A wind tunnel is a device that facilitates the study of fluid flow behavior around the geometry under investigation. However, not everyone has access to a wind tunnel, and some educational institutions have initiated their own projects to construct these facilities. In light of this, we aim to present a more accessible alternative for individuals who want to build their own wind tunnel. Consequently, we have designed and developed a low-cost, open-type wind tunnel, and have captured photographs to facilitate a qualitative comparison between the streamlines obtained through the tunnel and those generated by computational simulations. Our research findings confirm that the affordable wind tunnel can produce good results, thereby establishing it as a readily available resource for educational institutions.
