液体噴流の壁面への斜め衝突により形成される液膜流に及ぼす液体噴流の流動状態の影響

摘要

The liquid film-flow on the glass plate, formed by diagonal impingement of liquid jet, was observed experimentally. The effects of flow pattern of impinging liquid-jet upon the liquid film-flow were examined, utilizing the fact that the flow pattern of impinging liquid-jet varied with the liquid injection velocity from nozzle and the distance from nozzle-exit to impinging point. The distribution of film thickness was investigated qualitatively by means of the fluorescence method. Based on the results, the flow mechanism of liquid film on the plate was discussed.%液体噴流を様々な流動状態で壁面に斜め衝突させて壁面上の液膜流を観察すると共に膜厚分布を蛍光法で定性評価し，その結果を踏まえて液膜の流動機構について考察した.
