Relation Between Three-Dimensional Boundary-Layer Transition and Cavitation on a Yawed Cylinder

The relation between cavitation phenomena and three-dimensional boundary-layer transition on a 45-degree yawed cylinder was investigated using both wind tunnel and water tunnel facilities. Regularly arranged appearance of the cavitating bubbles on the cylinder surface seems to be caused by the cross...

Zusammenfassung:The relation between cavitation phenomena and three-dimensional boundary-layer transition on a 45-degree yawed cylinder was investigated using both wind tunnel and water tunnel facilities. Regularly arranged appearance of the cavitating bubbles on the cylinder surface seems to be caused by the crossflow vortices in the transition region of the same boundary layer. Physical properties like wavelengths are compared, and the results are in good agreement. Details of the two different phenomena are compared and discussed.
