Digital Aerodynamics

Conventional wind tunnels have a limited number of fans. They are generally programmed to all turn at the same speed, thus generating a uniform and permanent flow. We have developed a technology to shape the morphology of wind in space and time. It is based on a large number of fans (wind pixels), which are distributed arbitrarily in space and can be modulated individually in time. We will provide preliminary experimental measurements on the correlation between a given fan-speed distribution and the resulting flow pattern in the test section using PIV and multihole pressure probes.
