Turbulent Flows Liquid-gas

Wglu i = 0.2. The bubble mode is formed in this area of the liquid-gas flow. Further increase of the gas content in a flow does not influence the size of the dispersions (d 2 1-4 mm), which is evidently the effect of the transition to close-packed bubble (foam) mode. 

the ratio of gas and liquid-phase flow rates Wg lu i in tubular devices, as well as the dispersed system flow rate, exerts a substantial influence on the size of the dispersed inclusions. An increase of the volume-surface diameter of the dispersions, with an increase of the gas content (the growth of the Wg/wi ratio) can be compensated by the growth of the liquid-gas flow rate. Profiling of tubular turbulent device walls, to form diffuser-confusor transitions, is an effective way of reducing diffuser limitations for fast chemical reactions in the presence of an interphase boundary. 

The upper limit for an increase of the two-phase reaction mixture flow rate and the degree of reactor wall profiling, for the formation of finely dispersed systems, is determined by the fast growth of the input-output pressure drop, leading to an increase
