Preliminary Assessments of Combined Effects of Surface Tension and Viscosity on Bubble Column Hydrodynamics

Popis výsledku v původním jazyce

The present contribute reports results of combined effects of liquid features on the hydrodynamics of a lab-scale bubble column. In particular, the combined effects of viscosity - Newtonian fluid ? and surface tension were investigated. The experimentalapparatus consisted of a 10 L bubble column: a 120 mm ID, 1.8 m high Plexiglas column equipped with 0.4 mm needles gas distributor, free area 0.13%. The unit was equipped with gas flow controller, humidifier, diagnostic instrumentation, and data acquisition unit. The unit was operated batchwise with respect to the liquid phase at temperature of 25°C. The liquids investigated were aqueous solutions of sodium alginate and sodium chloride. The concentration of sodium alginate was increased up to 0.5%W, thesodium chloride up to 2 M. Solutions were characterized in terms of viscosity, surface tension, and conductivity. The viscosity ranged between 0.90 and 20 mPas, the surface tension between 68.4 and 71.9 mN/m, and conductivity between 0 a
