For a sharp-trailing edge airfoil at a small angle of attack, the flow cannot physically go around the sharp corner. Nature forces the flow to leave the trailing edge smoothly, with equal pressure on the top and bottom surfaces at that point.

Real aerodynamics is governed by the Navier-Stokes equations. These partial differential equations describe the conservation of mass, momentum, and energy in a fluid. The "real physics" argument acknowledges that air is . Inviscid (frictionless) theory can predict pressure distributions, but it cannot predict drag or stall. Without viscosity, a wing produces no drag but also cannot start or stop moving. understanding aerodynamics arguing from the real physics pdf

For those interested in learning more, there are a number of resources available, including textbooks, research articles, and online courses. One of the most useful resources is the PDF document "Understanding Aerodynamics: Arguing from the Real Physics", which provides a comprehensive introduction to the subject. For a sharp-trailing edge airfoil at a small

Finally, real physics today is argued through Computational Fluid Dynamics (CFD). But a good on aerodynamics will teach you the dangers of CFD: Without viscosity, a wing produces no drag but
