It looks all red on the right, which is mostly vapor. Maybe you need to use critical heat flux model to better capture this regime..

I agree that a wall temperature drop is expected in such cases. But also, there are too many interaction options to comment on.We already have two wall boiling verification cases (RPI - VMFL039 and critical heat flux - VMFL067) in the Fluent verifications manual with literature comparisons. You can check them for some pointers.
