A numerical moving boundary model has been developed to examine transient heat transfer and vapor-liquid displacement in impulse drying. The model, MIPPS, uses implicit, finitedifference forms of the mass, momentum, and energy conservation equations adapted for porous media. Predictions of water displacement, heat flux, and vapor pressure generation appear to be reasonable in light of available...

If so, then nappe emplacement occurred at T~475°C. of metamorphism played a significant role in the reaction and fluid history of the Rangeley Formation in southwestern New Hampshire, USA. Evidence for in situ melting includes: (1) the consistency among ...
