Default Natural circulation steam generator

I need to model a natural circulation steam generator.

for begining I want to model a vessel with an vertical open pipe in it. The pipe will be heated. So the water in the pipe will heat up and starts to evaporate. By differences in density the water will start flowing up the pipe. The pipe will be completely covered by water but in the vessel will be a substantially freeboard of steam over the water.

But I have no clear idea about it.

- What model to use: dispersed phase or free surface - Do I have to code heat- and mass-transfer myself or is there somthing implemented. - Is it possible to limit the condensation rate from bubbles to liquid - Is it possible to specify a slip for the bubbles.

thanks a lot in advance

martin
