Shear Layer and Secondary Vortical Flow beneath Free-Surface around Bow of Full-Form Ship Models〔含討論〕

概要

論文の詳細を見る
Discussions related to the existence of the free-surface shear layer around a surface piercing body and the formation of vortical motions at the bow are reviewed first based on the experimental evidences ever reported. Then to ex plain the mechanism of the vortical motions, a secondary flow theory is introduced. It is then explained that the free-surface shear layer is transformed into vortical motion due to the skewing of potential streamlines around a bow. Further, it is shown theoretically and experimentally that blunter bow form produces larger vortical motions.
