I am modelling the drying of a wet porous block using the Eulerian multiphase model in Fluent. The block is initially wet, with liquid water patched into the porous zone. One face is held at 80 °C, the opposite face is exposed to ambient air. The surrounding air is not modelled; the ambient side is imposed as a boundary condition. The temperature stays below boiling throughout, so the water leaves by evaporation into unsaturated air rather than by boiling.<\/p>\n
I have looked through the theory guide and a number of papers but have not been able to find a clear answer on which model applies here. Which option in the Phase Interaction panel should I use: Evaporation-Condensation (Lee model), Thermal Phase Change, or Species Mass Transfer?<\/p>\n","protected":false},"template":"","class_list":["post-462611","topic","type-topic","status-publish","hentry","topic-tag-eulerian-multiphase-model-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
