Tripped airfoil
WebApr 11, 2024 · 1 Answer. Tripping the boundary layer refers to the action of artificially transitioning a laminar boundary layer into a turbulent one. It can happen intentionally (via … Webfirst variable, ITRIP, specifies the boundary layer tripping of the airfoil. If ITRIP is set to 0, the boundary layer will not be tripped. A setting of 1 indicates “heavy” tripping, while 2 is for …
