Delta-wing vortex visualization using micro-sized water droplets generated by an ultrasonic humidifier
- 132 Downloads
An off-surface visualization method using micro water droplets and a laser beam sheet was developed. The average size of the water droplets generated by the home-style ultrasonic humidifier was about 5–10 μ. This method was pollution-free, eliminated the problem of toxicity, and provided a sufficient density of tracing particles for good visibility. The method was successfully applied to a visualization of the complex vortex flow of a double-delta wing with strake.
