Hi!!
I'm simulating a de-icing system on a wind turbine blade. This system consists of heating the blade once ice is formed. To visualize the results of my simulation I display the liquid fraction coefficient (please take a look at figure.1). I’ve used the “solidification-melting” model on Fluent but the problem is that I only want to apply it on the ice part and not on the air. You can see in figure.1 that air has a liquid fraction equal to 1 which means that it’s completely liquid but actually it is supposed to be a gas and here’s the issue.
Do you think I have to work in multiphase model as I have 2 fluids (Air and ice that is water material at minus 0 C°)?
Any suggestions?
Thanks a lot

Loffy
