Hi Foamers,
i'm trying to set up several testcases for the interFoam solver at the moment, in order to analyze it with respect to e.g. gravity currents.
The surface tension in an air water system can be set with the sigma term under transportProperties to a value of 0.07 kg/s².
But for the case of having a closed box with two liquids (in contact) inside i will have to define two values of surface tension or one value of interface tension, i think?! Is it right then to take only the difference of the two surface tension values and store it under the sigma term in the transport properties?
Let's say i'm using a water and saltwater system which is normally miscible (but interfoam treats it as unmiscible), so i should have to set the sigma to zero, right?
Thanks
