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:

    “Cursed be anyone who moves a neighbor’s boundary marker.” All the people shall say, “Amen!”
    Bible: Hebrew, Deuteronomy 27:17.

    A revolution is not the overturning of a cart, a reshuffling in the cards of state. It is a process, a swelling, a new growth in the race. If it is real, not simply a trauma, it is another ring in the tree of history, layer upon layer of invisible tissue composing the evidence of a circle.
    Kate Millett (b. 1934)
