Eksempler på mush

• An equation like holds in the liquid and solid parts of the mush as well as the pure-phase regions.

• First the smaller solid fraction decreases the latent heat that needs to be removed to grow a given depth of mush.

• Because of the fine structure, remains close to 0 in the mush and the average heat content is, approximately, proportional to the liquid fraction.

• In this mush, the temperature is between the solidus and liquidus.

• Melting starts at nucleation sites when reaches the critical temperature 0 at these points, and a mush forms.

• Then a macroscopic model for the mush is obtained by an averaging procedure.

• After about two days, only 9 large crystals protruded down to the mush-liquid interface.

• The conservation equations describing the interior evolution of the mush then have the form of forced diffusion equations.
