Laminar flow boiling of water in microchannel

ATIKADAR · July 4, 2017, 13:22

Hello everyone,

I am new in Ansys Fluent multiphase flow simulation. For my research I have to simulate laminar flow boiling (Sub-cooled and Saturated regime) in microchannel of hydraulic diameter of 500 micrometer and I am applying constant heat flux from the bottom. Inlet water temperature is 20 DegC. But I am confused which multiphase model of fluent would be most suitable for my simulation and should I need to write any UDF?

If someone can help me in this regard, then it would be very helpful for me?

As I know, there are some methods for phase change simulation by interface tracking such as VOF, LS or FT (front tracking) method.

Do you investigate on implementing of these methods by using UDF's into Ansys Fluent?
