internal aerodynamics and external aerodynamics. internal is related to flow of ducts and external to going away from the bodies.

AERODYNAMICS fits!
It falls under physics along with gravity.
I'm pretty sure it would be aerodynamics, which is a branch of dynamics, which is a branch of classical mechanics, which is one of the major categories of Physics. Perhaps one of our resident Physicists can offer a more precise answer.
Aerodynamics
Aerodynamics is a branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids. However if you were interested in the flow of fluid around a moving object, you simply stick it into a wind tunnel.
aerodynamics can be tested by a wind tunnel
the aerodynamics is the stupid answer that no one knows
Aerodynamics is the study of air flow around a moving object, and how that affects the object's motion. It is used often for airplanes and rockets, but also for automobiles, where reducing the drag (air friction) can improve performance and fuel efficiency. Aerodynamics is defined as "the branch of mechanics that deals with the motion of gases (especially air) and their effects on bodies in the flow." It includes the effects of pressure and air resistance.
