Skin Friction

Some articles on skin friction, friction, skin:

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 ... Under conditions 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 ...
Boundary Layer - Aerodynamics
... 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 ...

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)

    An old man, sir, and his wits are not so blunt as, God help, I would desire they were; but, in faith, honest as the skin between his brows.
    William Shakespeare (1564–1616)
