AN ADAPTIVE LEVEL SET METHOD FOR MOVING-BOUNDARY PROBLEMS: APPLICATION TO DROPLET SPREADING AND SOLIDIFICATION

A three-dimensional adaptive level set method has been developed for deformable free surface problems with or without solidification. In the new scheme, a three-dimensional multizone adaptive grid generation (MAGG) scheme is employed to track the moving boundaries and a level set method is used to capture the free surface deformation. The effectiveness and robustness of the algorithm are demonstrated by solving the droplet spreading and solidification problem, in which both free surface and solidification interface movements are important.
