Gustaf de Laval

Carl Gustaf Patrik de Laval ( pronunciation: [ ˌ gɵs tɑ ː ː ː v Doel aval ], born May 9, 1845 in Orsa, Sweden, † February 2nd 1913 in Stockholm) was an engineer and inventor.

Life

He came from a French family that had settled in Sweden. Among his many inventions in all fields of engineering is probably the most important an advanced centrifuge by Wilhelm Lefeldt for milk to separate the cream from 1878, for which he drive a DC -pressure steam turbine with patent of 1883 ( Lavalturbine ). Carl Gustaf Patrik de Laval invented a number of other typical machine elements, found the entrance to the turbine. They include the still very thin turbine shafts in oscillating bearings, which have their own resonance frequency below the speed.

Named after Carl Gustaf Patrik de Laval Laval nozzle is a 1883 developed for the admission of steam turbines with steam nozzle. Due to their geometry, which flows through the gas or vapor can be accelerated in its interior to supersonic speed without causing compression shocks. The speed of sound is reached exactly at the narrowest cross section of the nozzle.

Carl Gustaf Patrik de Laval ventured with his designs to the limits of his time considered for possible charges. One of its turbines he designed at the speed of 42,000 revolutions per minute of the order, which was considered by his contemporaries to be extremely dangerous.

De Laval founded in 1883 along with Oscar Lamm, the company AB Separator, which renamed itself in 1963 in Alfa Laval.
