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