Abstract: ABSTRACT:A new boundary element procedure which employs dipole-only singularities is
developed to predict the flow past a two-dimensional cavitating hydrofoil. In the
present approach, the unknowns in the discretized simultaneous equation system consist
of the dipole strengths at the control points on the wet surface of hydrofoil, the
adjusted cavity increments at the nodal points on the cavity surface and the constant
tangential speed on the cavity surface. As usual, the nonlinear iteration procedure is
adopted; that is, the dynamic and kinematic boundary conditions of the cavity surface
are specified on the correct cavity boundary which is a part of the flow solution and
unknown before the problem is solved. Some numerical experiments have been carefully
conducted. The results show that the present simpler approach successfully predicts
the flow, compared to the methods in the literature.
