Understanding Aerodynamics - Arguing From The Real Physics Pdf [verified]

Finally, a physics-based approach can lead to breakthroughs in our understanding of the underlying physics of the subject. For example, researchers have used CFD to study the behavior of air around complex geometries, such as aircraft and wind turbines.

Based on this report I made some Key points that are crucial to the understanding of understanding aerodynamics arguing from the real physics pdf

Understanding aerodynamics has numerous practical applications: Finally, a physics-based approach can lead to breakthroughs

A wing lowers the air pressure immediately above it. This causes the surrounding air to accelerate into that low-pressure zone. This causes the surrounding air to accelerate into

As McLean argues, this explanation is physically unfounded. Experimental data and computational fluid dynamics (CFD) demonstrate that the flow over the upper surface actually reaches the trailing edge significantly earlier than the flow beneath the wing. The error lies in assuming a cause-and-effect relationship that does not exist. The speed of the airflow is not determined by a transit schedule, but by the shape of the pressure field. The conventional approach puts the cart before the horse: the velocity difference is a result of the pressure field, not the cause of it.
