fluid transport mechanisms in microfluidic devices
... Electroosmosis refers to the bulk movement of an aqueous solution past a stationary solid surface, due to an externally applied electric field. Electroosmosis requires the existence of a charged double-layer at the solid-liquid interface. This charged double layer results from an attraction between ...

... flow changes from laminar to turbulent will depend to some extent on the shape of the object. As a rough guide, however, we can also say in this case that the transition from laminar to turbulent flow occurs around a value of 2000. With increasing Reynolds number, before the flow becomes fully turbu ...

Lift (force)
A fluid flowing past the surface of a body exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the surface force parallel to the flow direction. If the fluid is air, the force is called an aerodynamic force. In water, it is called a hydrodynamic force.
