Does what this guy is saying make any sense?
In his conclusions, PS, he reveals the complete poverty of his intellect, aerodynamics-wise.
There's no indication that he can discern the significance associated with the difference between a sub-critical Reynolds number laminar boundary layer, and a critical Reynolds number turbulent boundary layer.
The difference between a smooth or dimpled golf ball. A fatal mistake.
I recommend that all members and guests consider the difference between 'toy' CFD software, and something like Dassault's Exa Powerflow CFD, which requires a 120-core processor to run on.
If the presenter hasn't spent $ 300,000 on their CFD, I would consider their results extremely dubious.
