Boundary Layer - Boundary Layer Turbine

Boundary Layer Turbine

This effect was exploited in the Tesla turbine, patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. Boundary layer turbines are also known as cohesion-type turbine, bladeless turbine, and Prandtl layer turbine (after Ludwig Prandtl).

Famous quotes containing the words boundary and/or layer:

    Setting limits gives your child something to define himself against. If you are able to set limits without being overly intrusive or controlling, you’ll be providing him with a firm boundary against which he can test his own ideas.
    Stanley I. Greenspan (20th century)

    This world is run by people who know how to do things. They know how things work. They are equipped. Up there, there’s a layer of people who run everything. But we—we’re just peasants. We don’t understand what’s going on, and we can’t do anything.
    Doris Lessing (b. 1919)
