Laval, Carl Gustaf Patrik de


Born Sept. 5, 1845, in Orsa; died Feb. 2, 1913, in Stockholm; Swedish engineer and inventor (of French origin).

Laval graduated from a technological institute and the University of Uppsala (1872). In 1878 he designed a continuous-operation centrifugal cream separator. In 1889 he built an impulse steam turbine. Laval was the first to use a divergentnozzle, flexibler-shaft, equal-resistance turbine disk, facilitating the attainment of very high tip speeds (419 m per sec). His turbines made provisions for many new components, some of which are used in turbine-building today. Laval developed a theory of nozzles. Because of a number of design deficiencies and comparatively low output, Laval’s turbines were not widely accepted; however they played an important part in the development of turbine design.
