Claude Burdin
Claude Burdin (; 19 March 1788 – 12 November 1873) was a French engineer. Born in Lépin-le-Lac, Savoie, when it was known as the Duchy of Savoy, he was professor at the school of mines, École nationale supérieure des mines de Saint-Étienne, in Saint-Étienne. He became a French citizen on June 4, 1817. He proposed the concept and developed the term ''turbine'' from the Greek word τύρβη, meaning "whirling" or a "vortex". Biography Burdin was born on March 19, 1788, in the Duchy of Savoy. He was part of the class 1807 of the École polytechnique and the École nationale supérieure des mines de Paris. He became a professor at the École nationale supérieure des mines de Saint-Étienne. Burdin spent most of his engineering career in Clermont-Ferrand. In 1822, Burdin submitted his memo "Des turbines hydrauliques ou machines rotatoires à grande vitesse" (Hydraulic turbines or high-speed rotary machines) to the Académie royale des sciences in Paris. However, it wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...

Académie Des Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its British ...

Pontgibaud
Pontgibaud () is a commune in the Puy-de-Dôme départment in Auvergne in central France. It is located in the Massif Central region of France on the banks of the river Sioule. The area around the town was historically known for silver and lead mining. The Société des mines et fonderies de Pontgibaud exploited the lead-silver mines between 1852 and 1897. The remnants of Château-Dauphin, a 12th-century castle, are located in Pontgibaud. John Ruskin spent October 7, 1840 exploring Pontgibaud. He reckoned it "Altogether the happiest day, as far as employment or scenery can go, I have had for these long five years".The Dairies of John Ruskin.

Benoît Fourneyron
Benoît Fourneyron (31 October 1802 – 31 July 1867) was a French engineer, born in Saint-Étienne, Loire. Fourneyron made significant contributions to the development of water turbines. Benoît Fourneyron was educated at the École Nationale Supérieure des Mines de Saint-Étienne, a nearby engineering school that had recently opened. After he graduated in 1816, he spent the next few years in mines and ironworks. Around this time, a number of French engineers—including some of Fourneyron's former teachers—were starting to apply the mathematical techniques of modern science to the ancient mechanism called the waterwheel. For centuries, waterwheels had been used to convert the energy of streams into mechanical power, mostly for milling grain. But the new machines of the Industrial Revolution required more power, and by the 1820s there was enormous interest in making waterwheels more efficient.

Pierre-Simon Girard
Pierre-Simon Girard (4 November 1765 – 30 November 1836) was a French mathematician and engineer, who worked on fluid mechanics. Girard was born in Caen. A prodigy who invented a water turbine at the age of ten, he worked as an engineer at the École Nationale des Ponts et Chaussées. He was in charge of planning and construction of the Amiens canal and the Ourcq canal. He collaborated with Gaspard de Prony on the ''Dictionnaire des Ponts et Chaussées'' (Dictionary of Bridges and Highways, 1787). He wrote on fluids, and in 1798 he published a monograph, ''Traité analytique de la résistance des solides'' on beam theory, including possibly its first history, within the topic of strength of materials. The complicated beam equations were not of practical much use, since he applied Euler's non-linear theory. In 1799, he and other engineers and scientists accompanied Napoleon on his expedition to Egypt. He died in Paris, aged 71. Important works The 1798 monograph ''Traite An ...

Gaspard De Prony
Baron Gaspard Clair François Marie Riche de Prony (22 July 1755 – 29 July 1839) was a French mathematician and engineer, who worked on hydraulics. He was born at Chamelet, Beaujolais, France and died in Asnières-sur-Seine, France. Education and early works He was Engineer-in-Chief of the École Nationale des Ponts et Chaussées. The trigonometric and logarithmic tables of the cadastre In 1791, de Prony embarked on the task of producing logarithmic and trigonometric tables for the French Cadastre. The effort was sanctioned by the French National Assembly, which, after the French Revolution wanted to bring uniformity to the multiple measurements and standards used throughout the nation. In particular, his tables were intended for precise land surveys, as part of a greater cadastre effort. The tables were vast, calculating logarithms from 1 to 200,000, with values calculated to between fourteen and twenty-nine decimal places, (which de Prony recognized was excessively pre ...
