<p>Just did the Eulerian simulation, and the result gets even weirder. Still no vapor formed even when the evaporation frequency increased to 4 million s-1 even though the temperature around the inlet (note that this is water phase<\/em> temperature) increased to whooping 1500 K (I stopped the simulation when this happened, at physical time of around 0.1s.
