    Subsonic tunnel. Low-speed wind tunnels are used for operations at very low Mach number, with speeds in the test section up to km/h (~ m/s, M = ) (Barlow, Rae, Pope; ). They may be of open-return type (also known as the Eiffel type, see figure), or closed-return flow (also known as the Prandtl type, see figure) with air moved by a propulsion system usually consisting of large. Low-Speed Wind Tunnel Testing by Barlow, Jewel B., Rae, William H., Pope, Alan and a great selection of related books, art and collectibles available now at

      I am building a small wind tunnel, and I have a few questions about it. First: The Fan I am using produces cfm and is 12'' in diameter, I am going to narrow it down to 6''. The calculated wind speed that I got was km/h. Can anyone back me up on this? Second: When I use scale models. SUPERSONIC WIND TUNNEL Velocity in test section is upto Mach number of 5. Used to investigate the behavior of jet engines and military aircraft. HYPERSONIC WIND TUNNEL Velocity in test section ranges between Mach number 5 and Used in rockets and space vehicles. SUBSONIC WIND TUNNEL Velocity in test section is about m/s.5/5(1).

Great wind tunnel book. Very instructive. Contains everything one needs to know about low speed sub-sonic wind tunnel.

This is a must have book for anyone who is interested in wind tunnel theory, design and testing. Also, the book arrived within a couple of days, excellent service from ordering to receiving the items. I recommend it!Cited by:   The tunnel shown in the figure is a low-speed, closed tunnel which we are viewing from above.

The air inside the tunnel is made to move by the fan on the far side of the tunnel. Air continuously circulates through the wind tunnel, passing over the model that is mounted in the test section.

Low speed wind tunnel testing has evolved over the last century and has become a cornerstone in the development of aviation vehicles. Study of the effects of aerodynamics and its influence are substantial in the design of aircrafts and much fluid effect based engineering machines.

The forces involved in the dynamic interactions of fluids and solids have only begun to be lifted, therefore the. Low speed models can be a single airfoil model with high lift devices, or full configuration models with configurations to include landing gear and high lift devices.

Low speed models can be simple, straight-forward 3-D models fabricated from wood and composite materials or precision machined aluminum to meet customer's fast paced research. I've made a low speed wind tunnel for course project.

This is the first test of MH type airfoil at various angle of attack angles. Fog is generated with ultrasonic mist maker. Between and Eiffel ran about 4, tests in his wind tunnel, and his systematic experimentation set new standards for aeronautical research.

In Eiffel's laboratory was moved to Auteuil, a suburb of Paris, where his wind tunnel with a two-metre test section is still operational today. Figure 1. General layout of a closed circuit low speed wind tunnel.

Figure labels indicate the part name, according to standards. The main specifications for a wind tunnel are the dimensions of the test section and the desired maximum operating by:. The research results show that, the wire-driven parallel suspension system can be used in low-speed wind tunnel tests, and the method to calculate the model’s aerodynamic parameters by measuring the wire tension is feasible.
