hi friend . i hope all of you have the best days .

i have a problem to howis the way of modeling two phase a steam generator. that at the inlet subcooled water comes and at the end it must be change to superheated steam. but i cant acces to a correct answer.
my geometry simply a rectangular 2-D !!and i try to use the best setting.
my problem is that when i get a T-Y PLOT it just increase the temprature and there isnt a place that the fluid will be saturated and increase normally to end.

input vlocity : .3m/s
fluid pressure : 7.4 MP
input temprature: 251 * c

i choose vof model and set the steam fraction at the end equal 1 . and at the entrance is equal to 0.
