Question of properties in two phase solver
 
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
 
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?
