Investigation for Ignition of ADN-based Ionic Liquid with Visible Pulse Laser

Abstract

We evaluated the ignition probability of high-energy ionic-liquid droplet due to breakdown from visible pulse laser. The high-speed camera result, pressure profile, temperature trace from an R-type thermal couple, and radical measurement results using an image-intensifier charged-coupled device camera revealed the ignitability of this system. In addition, we simulated a simple thermal-diffusion model and investigated the temperature distribution for comparison with the experimental results. As a result, the probability of ignition due to a single pulse is low; however, potential for gasification and atomization of the ionic-liquid droplet is probable.
