In the $HOME/run/tutorials/twoPhaseEulerFoam/bed/constant, the dimension of phi is given as [0 0 0 0 0 0 0]. So it should be a dimensionless parameter. But in the OpenFOAM Guide, it is said phi is the flux, which equals density times velocity, rho*U, so the unit should be kg/s.m^2. Thus, i guess the two phi are different. What is the physical meaning of the first one?

Secondly, there are three parameters i do not understnad them well. They are eta, p and Fr. which are in $HOME/run/tutorials/twoPhaseEulerFoam/bed/constant. In which model they are used?

Lastly, what's the meaning of preAlphaExp, expMax and g0 in the file $HOME/run/tutorials/twoPhaseEulerFoam/bed/constant/ppProperties?

Could anyone tell me the role of ppProperties in the twoPhaseEulerFoam solver. What are the physical meanings of preAlphaExp, expMax and g0?
Farthermore, what is the usage of filterProperties?
