| Outline of Final Research Achievements |
This study aims the establishment of innovative environmental purification system by integrating the cutting edge technologies of ionic liquid electrospray and nano second pulsed discharge. Ultra-fine droplet generation process with Taylor cone formation followed by break up of liquid thread during ionic liquid electrospray was clarified by computational simulations. The ionic liquid generation system for CO2 absorption was developed. The fluid dynamical characteristics of electrospray was clarified through high speed imaging and droplet size distribution analysis by light scattering method. Furthermore, it was successfully demonstrated that the amount of CO2 absorption clearly increases by ionic liquid electrospray even under low CO2 concentration conditions.
