要約
(EN)
In a two-phase flow exciting force evaluation method, the surface of one of a plurality of tube bodies (3) is at least partially formed of a conductive material. The displacement or stress of the tube body (3) is then measured while being shaken by a shaking means (4). The void fraction of two-phase flow (F) flowing in the neighborhood of the tube body (3) is also measured on the basis of the difference between a voltage at a predetermined position on the surface of the tube body (3) and a reference voltage.
(FR)
L'invention porte sur un procédé d'évaluation de la force d'excitation d'un écoulement diphasique, dans lequel la surface de l'un d'une pluralité de corps tubulaires (3) est au moins partiellement constituée d'un matériau conducteur. On mesure ensuite le déplacement ou la contrainte appliquée au corps tubulaire (3) secoué par un moyen de secouage (4). On mesure également la fraction de vide de l'écoulement diphasique (F) s'écoulant au voisinage du corps tubulaire (3), sur la base de la différence entre la tension en un point prédéterminé de la surface du corps tubulaire (3) et une tension de référence.
(JA)
本発明の二相流励振力評価方法は、複数の管体(3)の一つを、少なくとも表面の一部を導通可能な材質で形成して、起振手段(4)によって振動させた状態で、該管体(3)の変位または応力を測定するとともに、該管体(3)の表面の所定位置における電位と基準電位との電位差に基づいて管体(3)近傍に流れる二相流(F)のボイド率を測定する。
