Polymer turbulence drag reduction — In 1948 Toms discovered by experiments that the addition of a small amount of polymer into a turbulent Newtonian solvent (parts per million by weight), whichresults in a Non Newtonian fluid solution, can reduce the skin fictional drag on a… … Wikipedia
D'Alembert's paradox — In fluid dynamics, d Alembert s paradox (or the hydrodynamic paradox) is a contradiction reached in 1752 by French mathematician Jean le Rond d Alembert.[1] D Alembert proved that – for incompressible and inviscid potential flow – the drag force… … Wikipedia
Aerodynamics — is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is closely related to fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is… … Wikipedia

Lift (force) — For other uses, see Lift. Boeing 747 8F landing A fluid flowing past the surface of a body exerts a surface force on it. Lift is the component of this force that is perpendicular to the … Wikipedia
geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… … Universalium
Oceanic physical-biological process — Sea water is 827 times denser than air Due to the higher density of sea water (1,030 kg m 3) than air (1.2 kg m 3), the force exerted by the same velocity on an organism is 827 times stronger in the ocean. When waves crash on the shore … Wikipedia

Terminal velocity — A free falling object achieves its terminal velocity when the downward force of gravity ( Fg )equals the upward force of drag ( Fd ). This causes the net force on the object to be zero, resulting in an acceleration of zero. Mathematically an… … Wikipedia
