Fluid Immiscibility

Hello there. I am new to 3d animations and blender.
I recently got an idea if I could animate mixing of water and oil (which are immiscible) in blender. But fluid simulation has got very less physical variables, in fact only viscosity. Although miscibility depends on liquid liquid pairs it shouldn't so hard to be implemented. Also many other variables could be there like volatility(example, lying water evaporates with time ), compressibility(example, fluid kept in smaller container splashes out when container breaks). That's all. Thank you.
