Abstract:

A new technique for flow visualization in air is presented. This technique employs small, neutrally-buoyant bubbles to map out particle paths and measure velocities, even in turbulent aerodynamic flows. An integrated visualization system was developed, comprised of a unique means to generate the bubbles, a compact illumination unit and specialized photography. Three test programs were carried out in subsonic wind tunnels to assess the system performance. The tests are discussed and an evaluation is given. A number of photographs illustrate the various facets of the technique.
