Abstract
Abstract A numerical experiment has been carried out to find a theoretically sound correlation relating mean bubble diameter in the main section of a bubble column to the liquid physicochemical properties (density, viscosity, surface tension), and the superficial gas velocity. A correlation has been proposed in the form: d 32 = 0.289 ρ L − 0.552 μ L − 0.048 σ 0.442 U G − 0.124 or, in an approximate, dimensionless form: F r = 0.6 U G 4 ρ L g σ 1 / 2 The values obtained from the above correlations are in good agreement with experimental values, obtained for seven organic liquids.
