Abstract
The present proposal considers the freesurface
effect on the high-speed hydrofoils.
Both cavitation and surface ventilation may
occur in the near fields of high-speed hydrofoils.
First, we studied the fully and partially
cavitating bubbles when the bubbles are near
the free surface and discuss the change of
hydrofoil lift due to cavitating bubbles and
free surface. The lifting force on such a composite
model is calculated under the freesurfaceassumption. All the computations are
based on nonlinear equations instead of the
conventional linear equations. In this project a
two-dimensional wedge entering a free surface
is considered.
