Abstract:
(EN) A flow-field measurement device that makes it possible to properly measure a flow field even in an environment that changes at a rate of approximately several Hertz. This flow-field measurement device includes a measurement unit that measures the flow velocity of fluid at a plurality of different measurement points in a plurality of measurement directions from a plurality of measurement positions on the bottom of a ship, and a flow-field calculation unit that calculates flow velocities at each of a plurality of target positions in the fluid by combining flow velocity components at a plurality of element positions located in the vicinities of the target positions. Each of the element positions is one of the predetermined measurement points on the predetermined measurement directions, and the flow velocity components are the flow velocity components measured at each of the element positions by the measurement unit.
(FR) L'invention concerne un dispositif de mesure de champ d'écoulement qui permet de mesurer correctement un champ d'écoulement même dans un environnement qui change à un taux d'environ plusieurs Hertz. Le dispositif de mesure de champ d'écoulement comprend une unité de mesure qui mesure la vitesse d'écoulement d'un fluide à une pluralité de différents points de mesure dans une pluralité de directions de mesure à partir d'une pluralité de positions de mesure sur le fond d'un navire, et une unité de calcul de champ d'écoulement qui calcule les vitesses d'écoulement à chacune d'une pluralité de positions cibles dans le fluide en combinant des composantes de vitesse d'écoulement à une pluralité de positions d'élément situées à proximité des positions cibles. Chacune des positions d'élément est l'un des points de mesure prédéterminés sur les directions de mesure prédéterminé, et les composantes de vitesse d'écoulement sont les composantes de vitesse d'écoulement mesurées à chacune des positions d'élément par l'unité de mesure.
(JA) 数Hz程度で変化する環境においても適切に流場を測定することを可能とする流場測定装置である。流場測定装置は、船底の複数の計測位置から、それぞれ複数の測定方向につき、前記各測定方向上での複数の異なる計測点における流体の流速を計測する計測部と、流体中の複数の対象位置につき、それぞれ、その近傍に所在する複数の要素位置における流速成分を合成して、前記各対象位置における流速を計算する流場計算部とを有する。前記各要素位置は、所定の前記測定方向上の所定の前記計測点であり、前記流速成分は、前記各要素位置においてそれぞれ前記計測部により計測された流速成分である。
