Plasma initiation simulations in homogenous liquids in response to ~ 3.0 – 5.0 ns voltage pulse is conducted. An in-house numerical framework consisting of a compressible fluid solver together with charged species conservation and Poisson's equation solver is employed for the simulations. The simulations are conducted for a needle-like powered electrode with two different voltage profiles – linear and exponential increase. The model predictions show that under the influence of nanosecond voltage...

Abstract This paper reports simulation results of oscillatory cool flame burning of an isolated, submillimeter sized n-heptane (n-C7H16) droplet in a selectively ozone (O3) seeded nitrogen-oxygen (N2-O2) environments at atmospheric pressure. An evolutionary one-dimensional droplet combustion code encompassing relevant physics and detailed chemistry was employed to explore the roles of low-temperature chemistry, O3 seeding, and dynamic flame structure on burning behaviors. For XO2= 21% and a rang...

During the last two decades non-thermal plasma discharges in and in contact with liquids have received significant attention in view of their wide range of application – extending from chemical analysis, medical, water treatment, fuel processing etc [1]. Despite the tremendous interest and advances attained in the experimental studies, modeling efforts providing a comprehensive understanding of the underlying physicochemical processes is limited. In the current work a mathematical model is devel...
