August 27, 2023 at 3:36 amAlwan HibatullahSubscriberI'm doing a cooling simulation of an electric motor that uses a water cooling system. but it seems there is a problem between solid to fluid domain interactions. where when heat flux is applied to the solid domain and propagates to the fluid domain, the results are invalid. but when my inter-domain connection is broken and heat flux is applied to the fluid domain, the result becomes validDoes anyone know how to maximize heat transfer between solid and fluid domains so that the Nusselt number results are valid?

Hi, I suggest you please check cource on conjugate heat transfer: Simulation Setup for CHT analysis | Ansys Courses
Hope this helps you.

thanks for the reply
but I used ansys fluent for this problem solver and not discovery, and I didn't understand when I saw a tutorial using ansys recovery because it's the first time I saw it. is there another video that is more specific to ansys fluent?

Here is the course in fluent related to conjugate heat transfer: Tutorial – Heat Transfer Modeling in Ansys Fluent | Ansys Courses
August 28, 2023 at 12:20 pmAlwan HibatullahSubscriberI've made sure that my fluent setup is correct, the solid to fluid domains are connected as coupled. but the results are still wrong, for example the heat transfer analysis on Re 500 should get a Nusselt number of 12, but what I get is only 5. is the problem with the meshing such as the inflation layer or some other part? considering that even I have used y+ = 1 but the result is still not valid
