You may have a look at my case, but I think you will learn nothing new. I acchieved some results using aritificially increased viscosity (factor 10000) on this small...

I did the same calculations with an initiated "square" drop which should reach its equilibrum state after a while. With "real" values for viscosity I observed a motion of the whole drop....

You can try to play around with the compression term in the alpha-equation. This term is intended to dampen numerical smearing of the interface and may as well have "improvement character" to...

If there is such a small viscosity there is even less damping to decrease the parasitic currents which will corrupt the solution.

I did exactly the same calcluation in my bachelor thesis and the results were equally bad. Furhtermore I did calculations following the works of S. Vincent and J.-P. Caltagirone....
