This is a steady state solution?

Yes, the bubble is expanding, the bubble is placed inside super-heated liquid, so the liquid at the interface is evaporating, and thus the vapor mass increases, which in turn increases the size of the bubble.

What i do not understand is the presence of the two counter-rotating vortices inside the bubble.
