Gustav de Laval
Carl Gustaf Patrik de Laval ( pronunciation : [ ˌgɵsːtɑːv ˈdœlːaval ], born May 9, 1845 in Orsa , Sweden , † February 2, 1913 in Stockholm ) was an engineer and inventor .
Life
His father was from France and his mother from Sweden. Of his numerous inventions in all areas of engineering, the most important is probably a further developed centrifuge by Wilhelm Lefeldt for milk for separating the cream from 1878, for whose drive he invented a constant pressure steam turbine with a patent from 1883 ( Laval turbine ). Carl Gustaf Patrik de Laval invented a number of other typical machine elements that found their way into turbine construction . They include the still very thin turbines are waves in oscillating bearings that their resonant frequency below the own speed have.
The notified by Carl Gustaf Patrik de Laval Laval nozzle is 1883 for the admission of steam turbines with steam developed nozzle . It is shaped in such a way that a gas or steam flowing through it can be accelerated to supersonic speed inside it without causing compression shocks. The speed of sound is reached in the narrowest cross section of the nozzle.
With his constructions, Carl Gustaf Patrik de Laval ventured to the limits of the loads considered possible at his time . He designed one of his turbines with a speed of 42,000 revolutions per minute on a scale that his contemporaries regarded as extremely dangerous.
De Laval founded the company AB Separator together with Oscar Lamm in 1883 , which was renamed Alfa Laval in 1963 .
In 1904 he was awarded the Grashof Memorial Medal from the Association of German Engineers .
