Omg bro u are amazing thank u so much do more video like that pls heat transfer from fluid to soild material if that possible thank u so much u are the best 😀👍
@@ansys_cfd But in most books, show if the flow is laminar and fully developed Nu number is dependent on the value of Din / Dout How can I know the length of the pipe to reach fully developed in different Reynolds number (laminar flow limit )
Hi friend, I think it is precisely for this reason, for high velocities the reynolds number increases and perhaps in your project is not laminar, it would be best to simulate it to know the length. Maybe you can find a book that indicates the length for different Reynolds numbers, but if you simulate it you can find a curve for all the cases. Regards

Thanks friend,

Please, How to know the appropriate length until the flow reaches fully developed in straight annular pipe ???
Hi friend;
It is advisable to do a simulation with a very long pipe and observe the length in the results where it has been fully developed.

Svp vous pouvez simuler les vibrations sous écoulement dans et autour des tubes des éhangeurs de chaleur ?
Hi friend, Yes, for that is necessary to combine ANSYS CFX with ANSYS MECHANICAL (FSI). I will try to make a video about phenomena . Best Regards
You can review this tutorial about FSI

@@ansys_cfd merci beaucoup pour votre réponse rapide, j'attends tes prochaines vidéo
You´re welcome friend.

Valeu!
can u please draw it in spaceclaim
