Free-Surface Boundary Layer and the Origin of Bow Vortices.

摘要

The boundary layer that exists due to the boundary conditions at a curved free surface of a viscous liquid ahead of a body in motion is analyzed. It is shown that surface tension and viscous effects are important and together explain the occurrence of vortices which have been observed on ship bows. The equations of the free-surface boundary layer have been derived and an integral method has been suggested for their solution. (Author)
