Symmetric plane flow past an airfoil https://album-of-cfm.com/chapters/02-laminar/fig23/ Mon, 28 Jul 2025 00:00:00 +0000 https://album-of-cfm.com/chapters/02-laminar/fig23/ ExperimentSimulation “An NACA 64A015 profile is at zero incidence in a water tunnel. The Reynolds number is 7000 based on the chordlength. Streamlines are shown by colored fluid introduced upstream. Fig 34. Boundary-layer separation on an inclined airfoil https://album-of-cfm.com/chapters/03-separation/fig34/ Mon, 28 Jul 2025 00:00:00 +0000 https://album-of-cfm.com/chapters/03-separation/fig34/ ExperimentSimulation “When the NACA 64A015 airfoil of figure 23 is raised to 5\(\degree\) incidence the laminar boundary layer separates from the rear half of the upper surface. The flow remains attached to the lower surface, from which it leaves tangentially at the trailing edge. Fig 85. Trailing vortex from the tip of a rectangular wing https://album-of-cfm.com/chapters/04-vortices/fig85/ Mon, 28 Jul 2025 00:00:00 +0000 https://album-of-cfm.com/chapters/04-vortices/fig85/ ExperimentSimulation “At 12.5\(\degree\) angle of attack the vortex is seen to separate well ahead of the trailing edge. The wing has an NACA 0012 profile and aspect ratio 4. At this Reynolds number of 10,000 the wake is laminar, in contrast to the opposite page.
