Skin Friction

Some articles on skin friction, friction, skin:

Boundary Layer - Aerodynamics
... the shear forces at the surface of the wing create skin friction drag ... This results in a lower skin friction due to the characteristic velocity profile of laminar flow ... This gives low skin friction, which is desirable ...
Parasitic Drag - Skin Friction
... Skin friction arises from the friction of the fluid against the "skin" of the object that is moving through it ... Skin friction arises from the interaction between the fluid and the skin of the body, and is directly related to the wetted surface, the area of the surface of the body that is in contact with the fluid ... As with other components of parasitic drag, skin friction follows the drag equation and rises with the square of the velocity ...
Oceanic Physical-biological Process - Drag
... In sea water, drag can be decomposed into two different forms skin friction and pressure drag ... Skin friction just like other frictional forces, skin friction is a consequence of the relative movement between the surface of the organisms and its fluid environment ... of low Re, where viscous forces dominate, the skin friction is apparent and is more important, although it is also present under high Re conditions ...

Famous quotes containing the words friction and/or skin:

    We have got onto slippery ice where there is no friction and so in a certain sense the conditions are ideal, but also, just because of that, we are unable to walk. We want to walk so we need friction. Back to the rough ground!
    Ludwig Wittgenstein (1889–1951)

    Racism as a form of skin worship, and as a sickness and a pathological anxiety for America, is so great, until the poor whites—rather than fighting for jobs or education—fight to remain pink and fight to remain white. And therefore they cannot see an alliance with people that they feel to be inherently inferior.
    Jesse Jackson (b. 1941)
