Thank you for your comment. I will be posting more videos, especially on the subject of coupled analysis of offshore wind turbines using mid-fidelity tools based on potential flow theories.
At the end of the video, seeing that u(y) is maximum (red color) almost all along the prism layer total thickness, can we conclude that the prism layer total thickness (delta) that we have assumed is higher than the boundary layer thickness? So should we reduce this total thickness (delta) and recalculate the number of layers (m) to simulate again?
Dear Jon Urcelay San Roman, As you mentioned correctly, the prism layer thickness appears to be greater than the boundary layer thickness and thus you can reduce the delta value, which consequently reduces the number of layers and the total cell count. However, in my experience it is best to keep this setting for the prism layer, which ensures high quality mesh close to the body to capture fluid flow characteristics. I hope this was helpful, Respectfully, Mojtaba Maali.
Dear Roberbeto Davila, Thanks for writing. One important reference for you to read is: White, F.M., Viscous Fluid Flow, 3rd edition, McGraw-Hill, 2006. I hope this was helpful. Respectfully, Mojtaba.
Dear Naji Ghandi, Thank you for your interest in this video. To tell you the truth, I have never applied this methodology to internal flows, but I believe it is applicable to both internal and external flows. Respectfully, Mojtaba Maali.

Idk if you will see this comm, but as a cfd engineer this channel helps me a lot! Hope to see more videos coming 😊

Absolutely Brilliant!
Excellent work! Thanks for making this vedio and presenting recommended approach to calculate these 3 important parameters for mesh generation.
I really appreciate for your excellent work.
Very helpful sir. Thank you very much for making this useful one...
nice..sir..meshing is heart of cfd....
very helpful. thank you for sharing this informative video with us.
Thank you for the thorough video!!
Excellent explanation!
excellent presentation. Thank you.
Excellent work
Very Well-done!!
Nice and awesome!

@@CFD_Mojtaba Thank you for your help!
GREAT TUTORIAL . Please simulate a soccer ball .
Excellent work! please can you attach references.

thanks ever so much for making such a video.
how about tubes? and internal flow?

@@CFD_Mojtaba so i will use it for internal flows as well. thanks for your immediate response.
best regards.
