The 4 foot long test section has excellent optical access for laser diagnostics and utilizes a dedicated 16 channel Netscanner PSI pressure transducer system to monitor total and static pressures of the tunnel and model. The tunnel has a high contraction area ratio resulting and low free stream turbulence and can operate up to a maximum Mach number of 0.4. This tunnel is particularly suited for diagnostic techniques which require particles or when conducting combustion experiments that result in products that need to be exhausted outside the laboratory. The 15”x15” wind tunnel at ARL is a fan-driven open-loop design that exhausts outside the laboratory. Contacts Faculty Researchersįacility and Equipment Description 15”x15” Subsonic Wind Tunnel Facility ARL has had a wide range of funding sources over the years including, AFOSR, ONR, NASA, DOE, Gulfstream, Rolls-Royce, 3M to name a few. Michael Selig and his students in this facility. Much of the performance data of low Reynolds number airfoils (UIUC Airfoil Data Site) and propeller performance curves (UIUC Propeller Data Site) were conducted by Prof. In recent years, research activities have included studies in unsteady aerodynamics, airfoil icing effects, flow control, motorsports aerodynamics, wind turbine blades, distributed propulsion systems, plasma assisted combustion, and turbojet bypass flows. The facility includes advanced instrumentation and flow diagnostics to allow researchers unique insight into the experimental models and flow regimes that are investigated. The action happens in the make_shape() function of the UiucAirfoil.The Aerodynamics Research Laboratory (ARL) houses subsonic wind tunnels utilized to conduct research in aerodynamics, propulsion, and fundamental studies in fluid mechanics.
