説明

In the previous work, the vertical distribution of the gas void fraction, the froth height and the mean gas liquid fraction ratio have been clarified theoretically for low clear-liquid height on a perforated plate under liquid stagnant flow.<br> In this work, in order to make sure of these theoretical results, experimental studies were performed in the air-water system. It was found that the theoretical values of the vertical distribution of gas void fraction and froth height agreed well with experimental values. Though the theoretical value of the mean gas liquid fraction ratio agrees with the experimental values better than do those obtained by Azbel and Kim, it does not always agree with the experimental values in a wide range of Froude number. Therefore, the empirical equations for the critical Froude number and the mean gas liquid fraction ratio in each region were obtained.
