ARELLANO, A.I; JARAMILLO, D; BARRON, M.A  y  PLASCENCIA, G. Momentum transfer in submerged gas injection using convergent-divergent nozzles. Lat. Am. appl. res. [online]. 2014, vol.44, n.4, pp. 295-299. ISSN 1851-8796.

Gas injection into liquids is common in many applications. Nozzles with simple geometries are used for injecting gases, this lead to some turbulence and thus different rates of mixing and residence times. In this paper we present a study on gas injection using convergent-divergent nozzles. Gas flow through nozzles with different diameter ratios has been studied. It was found that changes in diameter ratios have a definitive effect on the performance of these nozzles as the gas is injected into a liquid. Pressure measurements of the gas during injection were conducted so momentum transfer could be estimated; additionally high speed video allowed us to see the differences in the gas plumes as the different nozzles were used
