Hi guys,

i need to simulate a cooling jacket and i want to implicate the roughness of the tubes and the boiling phenomenon.
The problem is that the boiling temperature diverged and in don't know the reason. It is a steady mode simulation and the initialization mode is set to "uniform initialization". I applied the "Single Phase Boiling" only to the head and the model activates at the 400 iteration so the pressure is established.
The other settings I took from the Solution type "Cooling Jacket".

Does anyone know the problem here ?

kind regards
