Hello, I would like to know

Hello,

I would like to know if, it is possible of speficying the following in interFoam solver:
(1) a slip b.c on the walls (b*d(u)/d(y) = u_0, y = 0; b=slip length, u_o=slip velocity at the wall)
(2) Dynamic contact angle (|tan(theta)| = a*Ca^(1/3) - b*(lambda)^0.04*Ca^0.293; a = 7.48, b = 3.28, lambda = 10E-8, Ca = Capillary number)

I would request the interFoam users to share there thoughts on how to implement these in the exisiting interFoam solver (OF1.5).

Thanks,

a a saha.

Hi A A Saha regarding the (

Hi A A Saha

regarding the (2):

Take a look into the
/home/openfoam/OpenFOAM/OpenFOAM-1.5/src/transportModels/interfaceProperties/gam maContactAngle/

There lives the hierarchy for the existing models of contactAngle . Take a look in particular, the dynamic contact angle calcs.

Go through the code and see whether the framework will suit your requirements.

Kind Regards
Jaswi

Hi saha,

Did you implement your dynamic contact angle in interFoam. I would be so grateful if you share your experience with me.

Thanks,
MEhran
