Dyanmic Contact Angle Variation in Multiphase flow

I am trying to simulate a multiphase flow in a capillary tube. I have taken a capillary tube of 200mm length and 3mm diameter. I am solving the problem as 2D using level set(tpf). In my problem initially there is a water plug of length 30mm followed by a toluene plug of 15mm length and again there is water for the rest of the tube. So, toluene is in between water. So, two interfaces are formed. At the inlet, the velocity is fully developed flow(parabolic) and the outlet is at 0 Pa pressure.

Now, at the two interfaces the contact angle will vary dynamically and for this I have already derived the relations. But, where to put these two variations is my issue. Can anybody help ?
