Hello everyone.
Can someone help me with information about capillary driven flow modelling in CFX? I am looking for some step by step simple tutorial about rectangular speciment saturation. The exact capillary effect in one vessel is wellknow but how to make macromodel. The input parameters should include porosity and permeability. Any suggestions? Thanks |

No step by step tutorials exist.
Are you talking about free surface/capillary modelling in general, or capillary flow in porous media? |

I am interested axactly in capillary flow in porous media. But when I am trying to simulate it I always find the ways when I need to valuate pressure or flow speed as boundary condition for inlet. For my problem of saturation I dont know the value of pressure or flow speed. I know just that part of boundary is wet (fluid fracture = 1) and thats all. |
