Abstract
The effect of various factors on the size of bubbles from single submerged orifices ranging from 4 to 16mm in diameter was investigated. The twelve kinds of liquid listed in Table 1 were employed for the experiment. The results are represented by using mean geometric diameter (d) and standard deviation (s), because the bubbles formed are almost in cornformity to the logarithmic probability distribution. In the experiment in which gas chamber volume (Ve) is kept to a small value, (d) increases at Nw16, , with increasing gas flow rate. The dependence of bubble size on Ve shows three distinct regions: (1) Ned is independent of Ve (2) 1<Ned corresponds to Ve (3) 9<Ne: d is independent of Ve The reason is that the inner pressure of bubbles varies with the diameter of the bubble attached to the orifice.Keywords
