Spontaneous Phase Separation of Immiscible Fluids

Spontaneous Phase Separation of Immiscible Fluids

Phase separation occurs when a binary system is quenched from its stable, homogeneous one-phase state into the two-phase region of its phase diagram. The spontaneous separation of two immiscible fluids is sometimes referred to as spinodal decomposition. Each phase tends to separate into pure components.

This benchmark model takes two initially mixed, immiscible phases and observes their separation into pure components. It demonstrates how to use the Phase Field application mode to model the process of phase separation.

Plot of the phase field variable, the two fluids tend to separate into distinct phases.
