Title (EN) OPTICAL PROBE FOR DETERMINING QUANTITIES OF A TWO-PHASE FLOW
(FR) SONDE OPTIQUE POUR LA DETERMINATION DE GRANDEURS D'UN ECOULEMENT BIPHASIQUE
Abstract: front page image
(EN)The invention relates to an optical probe comprising an optical fibre (51) associated with a conical tip (7), made of sapphire or diamond, with a circular base (71) and having, between the base and the end, an annular groove (73) with a curved bottom (731) or at least one axisymmetric shoulder. The invention also relates to a method and a system for determining characteristic quantities of a two-phase flow using such a probe.
(FR)L'invention concerne une sonde optique, comportant une fibre optique (51) associée à une pointe conique (7), en saphir ou en diamant, de base (71) circulaire et comportant, entre la base et l'extrémité, une rainure annulaire (73) à fond (731) courbe ou au moins un épaulement de révolution. L'invention concerne également un procédé et un système de détermination de grandeurs caractéristiques d'un écoulement biphasique utilisant une telle sonde.
