two-phase flow void fractionとは 意味・読み方・使い方

METHOD FOR INSTANTANEOUSLY MEASURING VOID FRACTION IN FLOW PATH CONTAINING GAS-LIQUID TWO-PHASE FLOW例文帳に追加

気液２相からなる流路内のボイド率を瞬時に計測する方法。 - 特許庁

The relation between the void fraction and capacitance of a plurality of two-phase flows where mixing ratio of air/water is changed is previously determined as a measurement characteristic expression, and then the capacitance measurement result about unknown air/water two-phase flow is compared with the measurement characteristic expression, thereby determining the void fraction.例文帳に追加

予め、空気／水の混合比を変化させた複数の二相流について、ボイド率と静電容量との関係を計測特性式として求めておき、次に、未知の空気／水二相流についての静電容量測定結果を計測特性式に照らすことによりボイド率を求める。 - 特許庁

With this method, void fraction variation in a flow path containing gas-liquid two-phase flow is instantaneously measured by providing a center line electrode in the flow path installing a plurality of rods and metal made wall electrode on the wall in the flow path and measuring electric resistance in the flow path.例文帳に追加

複数のロッドを内装した流路内に中心線電極を設け、その流路内壁に金属製壁型電極を設けて流路内の電気抵抗を測定することにより、気液２相からなる流路内のボイド率の変化を瞬時に計測する方法。 - 特許庁
