Velocity along the airfoil surface

Blue represents the velocity along the upper surface and red along the lower surface. The point of stagnation is shown as a gray circle near the leading edge. If the viscous option has been selected, the approximate transition points are shown on both the velocity and on the surface.

The transition from laminar to turbulent flow is shown by the first blue or red circle. The point of separation (if any) is shown by the next blue or red circle.

The displayed results as a function of the angle of attack are a linear interpolation of the calculated values.

The Display Scale slider may be used to increase or decrease the relative size of the display.

Calculated values along the surface may be examined by scrolling cursor while holding down the left mouse button. A vertical line will show the selected chord location.
