Default Boundary conditions for Two-phase Flow with Different Inlet Pressures

cnkulkarni is on a distinguished road
I am working on a 2D channel flow of air and water flow using interFoam as the solver.
Some part of the inlet is the inlet for water, whereas the remaining part is inlet for air.
The case requires air to be coming in from a higher pressure than water (10 times more).
Velocity of the water is fixed. flow is laminar always.
I have tried fixedValue, totalPressure for the boundary conditions at air and water inlet of the file p_rgh; but both of them yield non-physical results.
I wish to know what would be suitable boundary conditions for such a flow.
I am attaching the image of the domain for better clarity.
Please help me if possible.
Thanks a lot!
