Kutta Condition
On a streamlined body fully immersed in a potential flow, there are two stagnation points—one near the leading edge and one near the trailing edge. On a body with a sharp point such as the trailing edge of a wing, the Kutta condition specifies that a stagnation point is located at that point. The streamline at a stagnation point is perpendicular to the surface of the body.

Famous quotes containing the word condition:
“We have imagined ourselves a special creation, set apart from other humans. In the last twentieth century, we see that our poverty is as absolute as that of the poorest nations. We have attempted to deny the human condition in our quest for power after power. It would be well for us to rejoin the human race, to accept our essential poverty as a gift, and to share our material wealth with those in need.”
—Robert Neelly Bellah (20th century)
