This slow-mo video, taken with smoke for visualization purposes, was obtained in the Caltech Real Weather Wind Tunnel system at significantly lower flow speed than the actual experiments.

he velocity is up to 50 m/s. The small wind tunnel is equipped with an external three-component force balance. PC is used for tunnel control and data acquisition. Other facilities include a small ...

Once you’ve got yourself a wind tunnel, you might want to start thinking about some flow visualization, which gets really exciting.

An open-circuit wind tunnel with a length of 4m and a cross section of 0.25m x 0.25m. Smoke is used for flow visualization around building models of various configurations. It is used primarily for ...
