Abstract:
A new numerical method is presented for simulating droplet impact and icing on solid surfaces.  The four materials, air, liquid, ice, and solid are represented using the coupled level set and moment-of-fluid interface reconstruction method.  The moment-of-fluid interface reconstruction algorithm has volume and linearity preserving properties using only local information within a computational cell, and for any number of materials. The ghost fluid numerical method has been implemented so that solutions are consistent with the jump conditions at the interface(s) taking into account surface tension, triple point conditions, contact line dynamics, phase change, expansion of ice, and heat release.  Results are presented in 2D, RZ, and 3D coordinate systems which demonstrate the effect of surface wetting properties on the resulting drop impact and solidification.

The presented numerical method is general enough to be applied to many scenarios where materials change phase.  An example of the application of the new method to nucleate boiling problems in microgravity environments
will be presented too.
