“…Because of their ability to combine various types of data, wind tunnels prove to be a critical device in the efficient and detailed design procedure of anything that involves fluids. [21] Thus, across a wide variety of manufacturing and research applications, experimental explorations remain the mainstay for collecting evidence for designers to produce detailed performance and final decisions.…”

“…This is really helpful for a tunnel used for development experimentation with a very high usage rate (2, 3 times for 5, 6 days/week). [21,45,9,47,7] Drawbacks 1. A huge amount of initial investment (due to return ducts and corner turning vanes) 2.…”

“…A technique of cooling would be mandatory for high utilization of the tunnel. [21,45,9,47,7] Open Circuit Wind Tunnel (OCWT)/ Eiffel Type With an Open circuit wind tunnel, it is possible to achieve high performance, and even save space and construction cost. In essence, an open circuit wind tunnel is actually a closed circuit wind tunnel with a shabbily designed return leg/lag.…”

“…4. OCWTs would need higher energy to run, which is a contributing factor to the high utilization rate in developmental experiments [21,45,9,7,47, 10] 5. They are generally placed in large rooms, as are sensitive to impediments in room, like furniture or walls which give rise to adverse effects in flow.…”

Wind tunnel (WT) is a device that artificially produces airflow relative to a stationary body and measures aerodynamic force and pressure distribution, simulating the actual conditions with an important aspect of accurately feigning¬ the full complexity of fluid flow. The aim of the present study is to design the three dimensional geometry of a small, open-circuit (also known as Eiffel Type), and subsonic (low speed) wind tunnel (WT) capable of demonstrating or acting as a vital tool in aero-mechanics research. The project and fabrication itself, poses as an onerous task with the cynosure/central theme being the delineation/depiction of wind tunnel components such as Test Section, contraction cone, diffuser, drive system and settling chamber.

“…Because in the confuser due to the action of fan oscillations and a sharp drop in pressure there is a maximum deformation. The development of the classic construction of a wind tunnel of closed type is presented in the article [4]. It shows the construction features of a low-speed wind tunnel of closed type.…”

Nowadays, the development of wind tunnels for the study of various aerodynamic phenomena is actively developing. It is possible to generate a highly laminar flow only under the condition of structural stability of the construction parts of the wind tunnel under the action of sharp pressure drops. The aim of this research is to investigate the deformation and displacement of the structural parts of the developed wind tunnel capacity of 55 kW depending on the velocity of the generated airflow. To estimate the amount of deformation and mutual displacement of the structural elements of the wind tunnel depending on the airflow velocity, we used the ARAMIS optical system.
