    Delaying boundary layer transition and flow separation

    Hi boneh3ad, I've got a few more questions if you'd be kind enough to help me out, related to drag. I understand skin friction drag reasonably well, but I'm having a bit of trouble understanding pressure drag in its entirety. So for an inviscid irrotational flow, there will be no pressure...

    Delaying boundary layer transition and flow separation

    Thanks, all very interesting. And I agree, I wouldn't fancy working in a field that will some day be made completely redundant :-p

    Delaying boundary layer transition and flow separation

    Great post boneh3ad! I'm very new to fluid mechanics, but I'm interested in the step between the closed NS equations and the point at where it becomes a problem with multiple possible solution modes. Is this what turbulence does? And does this mean that DNS is not applicable to turbulent...

    Simple Deflection of a Cantilever Frame. .

    How would I go about splitting it into 2 beams? If I make AB a simple cantilever beam, what forces/moments would be acting at point B?
