Applications of the diffuse-interface method

In this talk I will present some of our recent applications of diffuse-interface modelling (DIM). This technique is an elegant approach to track moving interfaces in time, including topological changes in multi-phase systems like breakup and coalescence. Briefly, the theory behind DIM will be reviewed and some details will be discussed on the numerical methods involved.

The following applications will be discussed:
The rheology and morphology of polymer blends in shear flow.
Micron-sized drop spreading and impact on smooth and non-smooth substrates.
Phase separating blends in two-component injection moulding.
Marangoni convection of polymer-polymer drops (a ternary system)
