A Study of Cavitation Bubble Temperatures in Room Temperature Ionic Liqiud

Abstract:

Room temperature ionic liquids (RTIL) have been developed to a central point of interest in both academia and industry. RTIL is non-volatile, thermally stable and non-flammable solvent. These properties can offer a green opportunity for sonochemical reactions. In this work, the cavitation bubble temperatures have been measured using methyl radical recombination (MRR) method. The temperatures measured in ImPF₆ are in the range of 3000 4000 K. Additionally, based on the bubble dynamic equation with the consideration of liquid surface tension, viscosity and radiative resistance, numerical simulations have been carried out to investigate the cavitation bubble dynamics. The difference of the temperatures obtained from the experiment and numerical simulations has been interpreted.
