Title (EN) APPARATUS AND METHOD FOR CHARACTERIZING TWO PHASE FLUID FLOW
(FR) APPAREIL ET PROCÉDÉ PERMETTANT LA CARACTÉRISATION D’UN ÉCOULEMENT DE FLUIDE BIPHASIQUE
Abstract: front page image
(EN)An apparatus (and corresponding method) for characterizing the fluid properties of a two phase fluid, e.g. steam and water, includes a restriction element (51), e.g. orifice plate or nozzle, along the flow path of the two phase fluid. At least one temperature sensor (55A, 55B) measures temperature of the two phase fluid flowing through the restriction element. A pressure sensor (57B) measures the pressure downstream of the restriction element. Time-of-f light measurements of pulses passing through the two phase fluid are made (59A, 59B). The speed of sound within the two phase fluid is calculated from the time-of-f light measurements. At least one fluid property (e.g., a vapor phase fraction) of the two phase fluid is calculated from the measured pressure, the measured temperature, and the calculated speed of sound.
(FR)La présente invention concerne un appareil (et un procédé correspondant) permettant la caractérisation des propriétés d’un écoulement de fluide biphasique, par exemple la vapeur et l’eau, comportant un élément d'étranglement (51), par exemple, une plaque ou une buse à orifice, le long du chemin d’écoulement du fluide biphasique. Au moins un capteur de température (55A, 55B) mesure la température en aval de l’élément d'étranglement. Un capteur de pression (57B) mesure la pression en aval de l’élément d'étranglement. La mesure du temps de vol des impulsions traversant le fluide biphasique sont effectuées (59A, 59B). La vitesse du son dans le fluide biphasique est calculée à partir des mesures du temps de vol. Au moins une propriété de fluide (par exemple, une fraction de phase vapeur) du fluide biphasique est calculée à partir de la pression mesurée, la température mesurée, et la vitesse du son calculée.
