Sir! Can you continue this series of videos pls:)? There are not enough sources except you,sir!

[@Simulation-Engineer]

Yes sure I will be doing soon some new tutorials. Thanks for the feedback and nice comment.

[@blackish3115]

@@Simulation-Engineer Thank you so much sir! I have an project to make a UAV so i would love to listen your advices about making UAV too.

Hi sir,
Can you explain how I can choose ncrit according to Reynolds number
ex: Re = 24000000 => Which value should I choose for Ncrit
Thank you

[@Simulation-Engineer]

Ncrit is critical number in e^N theory (the disturbance in linearized bl equations grows e^N times before passing to turbulence).
----------------------
Ncrit values:
sailplane 12-14
motorglider 11-13
clean wind tunnel 10-12
average wind tunnel 9
