Droplet impact on a concave wall in a rotating gas flow field

The behavior of liquid droplet impact on the concave wall in a rotating flow field is vital for swirl-vane separators and spiral fuel bundles in nuclear reactors. To reveal the collision mechanism of the droplet on the concave wall in a rotating flow field, a test rig for swirl vane separators is de...

Zusammenfassung:The behavior of liquid droplet impact on the concave wall in a rotating flow field is vital for swirl-vane separators and spiral fuel bundles in nuclear reactors. To reveal the collision mechanism of the droplet on the concave wall in a rotating flow field, a test rig for swirl vane separators is developed. The impacting behaviors of droplets on a concave wall with a diameter of 130 mm are recorded by a high-speed camera over wide ranges of diameters (0.2 mm
