Wrong results from thermosiphon model
-

Hello Everybody!
I am modeling a thermosiphon for cooling. The measurement for the given geometry portends 300 W heat transfer power. I developed first a 2D model and the mean power in time was in good aggreement with the measurement. I have done after the 3D model. You can see the geometry with dimensions below. But unfortunately the heat transfer power remained 2 order of magnitude lower from the expected 300W. Could anybody give me some tip for the reason ? If it necessary I will upload the settings images from Fluent. Thank you for your help!
