I want to simulate droplet with different contact angle in palabos. For this purpose, I change multicomponent2d example rayleigh-taylor (change initial density and location of each component) and apply wetting properties to walls for obtain droplet near the wall. After some iteration density in droplet (heavy fluid) quickly decrease .For example initial density in droplet is 2, after some iteration it’s density reduce to 0.5 and reach to equilibrium to another component(light flow has initial density 0.6 ). I think it does not true because density in core of droplet must be constant(rho=2) . What shall I do to make sure my simulation is correct and my droplet have a correct density.?
Somebody please explain to me what am I doing wrong?
