I was wondering how fluent handles heat transfer at two sided walls where fluid meets solid. I can't seem to find anything about it in the manual.
Does it use some kind of correlation to find a heat transfer coefficient from the Nusselt number or does it assume the wall temperature is equal to the temperature at the very edge of the fluid? Something else? I have no idea how this condition works, which makes it difficult to understand if there are limitations associated with using it. |

It will calculate a heat transfer coefficient given the flow characteristics, then it will solve the convective heat transfer equation.
Which coorelation it uses to solve for h; i don't know. |

Thank you for the reply. I has assumed it used something similar to the Dittus-Boelter equation but was unsure.

The same question for the 2-sided wall heat transfer.
Who knows how to calculate the heat transfer from fluid to solid, or knows the coupling mechanism (such as related control equations or calculation basis). thank you. Quote:
