Gas Dispersion Phenomena and Mixing Characteristics Under Gas injection Through Slot Mozzle Suberged in Water

摘要

The dispersion behavior and the bath mixing intensity were investigated by injecting gas through the slot nozzle into wate. A high sped video recording system was used to measure the bubble diameter. The mixing time was measured by using an electrical conductivity method. Measurements were conducted under various gas flow rates and bath depths. The comparison of mixing time between a slot nozzle and a single circular nozzle was examined. The results were discussed in terms of specific power of injected gas.
