| Summary: | We propose to model ice shedding trajectories by an innovative paradigm that is based on
cartesian grids, penalization and level sets. The use of cartesian grids bypasses the meshing issue, and
penalization is an efficient alternative to explicitly impose boundary conditions so that the body-fitted
meshes can be avoided, making multifluid/multiphysics flows easy to set up and simulate. Level sets
describe the geometry in a nonparametric way so that geometrical and topological changes due to
physics and in particular shed ice pieces are straight forward to follow. The model results are verified
against the case of a free falling sphere. The capabilities of the proposed model are demonstrated on
ice trajectories calculations for flow around iced cylinder and airfoil. |
