ガス・ジェットによる液面凹み現象に及ぼす雰囲気圧力の影響

抄録

Through the modification of gas jet theory by BRADSHAW et al, a mathematical representation that is capable of expressing the influence of pressure in atmosphere has been proposed for the dynamic characteristic of gas jet. Experimental model tests gave also been conducted for the confirmation of the proposed model.
The results are summarized as follows:
(1) The mathematical model is found to give semi-quantitative agreement with results of experimental model tests.
(2) The results of the model tests indicate that the gas jet under the reduced pressure transports the momentum to the liquid surface with less energy loss than that under the atmospheric pressure. The cavity gets, with the decrease of pressure in atmosphere, accordingly.
(3) The approach outlined here seems to indicate an attractive suggestion for the understanding of the mass transfer in gas jet/liquid reaction.
