Comparison of mist generators between twin fluid water suction type and single fluid swirl type

Abstract

Sadatomi and Kawahara invented a multi-fluids mixer which is categorized as a twin-fluid type but have a merit of water suction type. The mixer is usable to generate microbubbles, etc. besides mists, fine droplets. In the mists generation, pressurized air alone is supplied because water can be sucked automatically by a negative pressure arisen downstream from the orifice in the mixer. The objective of the present study is to compare the performance between the above twin-fluid type atomizer and a common single-fluid swirl type atomizer studied in the present experiments. The comparison results showed that the twin-fluid type was superior to the singe-swirl type in the performance of CO 2 adsorption by the mists.The CO 2 adsorption rate by the twin-fluid type was about twice. Such results on the experiments and the comparisons are described in this paper.
