This Miniature Experimental Subsonic Wind Tunnel is designed for studying airflow patterns and analyzing the behavior of objects moving through air, using a data acquisition system for real-time analysis, the data acquisition system is optional. It helps students understand basic aerodynamic principles by observing how air moves around stationary models. This wind tunnel is an “Eiffel” type open system, where air is drawn in, accelerated, and directed around models like aerofoils within a measurement section. After passing the models, the air slows down in a diffuser before being expelled back into the atmosphere by a fan. The tunnel’s nozzle and flow straightener ensure a uniform, low-turbulence airflow in the square measurement section.
The system can generate air speeds of up to 20 m/s, powered by an energy-efficient fan with a variable-speed drive, which is available as an optional accessory. Aerodynamic forces such as lift and drag are measured using a two-component force sensor and displayed digitally. Air velocity is shown via an inclined tube manometer or a digital display through differential
pressure transducer. Angle of attack can be set manually or digitally when DAQ option is selected With an optional Data Acquisition (DAQ) system, measured parameters like pressure, velocity, angle, and force can be transferred to a PC for analysis using dedicated software. The wind tunnel comes with a variety of accessories for conducting experiments on lift, drag, and streamline visualization. Comprehensive instructional materials guide students through these experiments step by step.
