Numerical Methods for Solving Free-Boundary Problems (Part I of II)

The speakers in this minisymposium will present innovative numerical methods for solving interfacial fluid dynamics problems characterized by large density and viscosity jumps (e.g. air/water) and stiff singular source terms such as those due to surface tension. Problems with these features are extremely important in science and industry. Solidification in castings, the collapse of a cavitation bubble near a rigid boundary, spray deposition and jets are just a few examples. The methods used to solve these problems include level-set, volume-of-fluid, phase-field, front-tracking and boundary integral methods. Important issues in computing these flows include the solution of an elliptic equation with discontinuous coefficients and
the tracking of complex material interfaces.
