| Abstract: | The hydrodynamic problem of collision of an axisymmetric water block and solid boundary has been analyzed based on the velocity potential theory. The three dimensional axisymmetric hydrodynamic problem is converted to a quasi two dimensional one and is solved in axisymmetric coordinate system using the boundary element method. Numerical simulations are made for collision of a solid cone with a liquid cone or a spheroidal liquid block. The results in the former are compared with those obtained from similarity solution and excellent agreement is found. Numerical results are then presented for the collision between different solid cones and various spheroidal liquid blocks. |
