Hello Everyone, I am trying to simulate a Y shaped channel using VOF method in Ansys Fluent. Discretization of the model has been done. Inlet velocities of both dispersed and continuous phase are calculated using Capillary Numbers. I have considered no slip boundary condition at domain wall. Hereunder is the method I have applied while performing the simulation:

Method- a)pressure velocity coupling scheme= coupled with vof
b) Discretization method- Green gauss cell discretization method
c) Pressure-PRESTO
d)Momentum-Second order upwind
e) Volume fraction-compressive
f) Transient formulation-Bounded second order implicit

Provided a suitable Residual of 10^-6, Time step size- 100 and Max iterations/step size-20.

My objective is to form a Janus Droplet. But droplet is forming but no janus droplet formation took place applying this methodology. Can anyone please throw a light on where I am doing wrong or is there any other process to form a Janus droplet.
