DYNAMIC SYMMETRY TURBINES

TURBINES À SYMÉTRIE DYNAMIQUE
(ES)
TURBINAS DE SIMETRÍA DINÁMICA
Abstract:
(EN)
The invention relates to the design of turbine rotors which operate both as a pump and a motor and which are essentially made by joining two types of plates, namely a pressure plate and a suction plate, the shapes of which are based on the criterion of dynamic symmetry, whereby a theoretical dynamic symmetry surface (1) has a twisted shape, such that a current of fluid (2) can be conveyed along one of the faces thereof, following a pre-determined path and exerting thereon pre-determined stresses, while at the same time another current of fluid (3) can be conveyed along the other face thereof, following another path symmetrical to the first and exerting thereon other stresses symmetrical to the first. The invention provides different structural solutions that demonstrate the application of the criterion of dynamic symmetry to the design of radial, axial and mixed flow turbines.
(FR)
La présente invention porte sur la conception de rotors de turbine qui fonctionnement à la fois en tant que pompe et en tant que moteur et qui sont fabriqués essentiellement par la liaison de deux types de plaques, une plaque de pression et une plaque d'aspiration, dont les géométries sont dérivées du critère de symétrie dynamique selon lequel une surface à symétrie dynamique théorique (1) présente une forme gondolée qui permet de conduire un courant de fluide (2) par une de ses faces, décrivant une trajectoire déterminée et exerçant sur le fluide des efforts déterminés, et qui permet de conduire simultanément un autre courant de fluide (3) par son autre côté en décrivant une autre trajectoire symétrique à la première et en exerçant sur le courant d'autres efforts symétriques aux premiers. La présente invention propose diverses solutions constructives correspondant à l'application du critère de symétrie dynamique pour la conception de turbines à flux radial, axial ou mixte.
(ES)
Se describe el diseño de rotores de turbina que funcionan a la vez como bomba y como motor, fabricados esencialmente mediante la unión de dos tipos de láminas, uno de presión y otro de succión, cuyas geometrías se derivan del criterio de simetría dinámica según el cual una superficie de simetría dinámica teórica (1) tiene una forma alabeada tal que permite conducir una corriente de fluido (2) por una de sus caras describiendo una determinada trayectoria y ejerciendo sobre ella unos determinados esfuerzos, mientras que al mismo tiempo permite conducir otra corriente de fluido (3) por su otra cara describiendo otra trayectoria simétrica a la primera y ejerciendo sobre ella otros esfuerzos simétricos a los primeros. Se proponen diversas soluciones constructivas comprobando la aplicación del criterio de simetría dinámica al diseño de turbinas de flujo radial, axial o mixto.
