Modeling And Simulation Of \Sub-Microsecond Electrical Breakdown In Liquids With Application To Water, Jun Qian
Electrical & Computer Engineering Theses & Dissertations
In this dissertation, the inherent physics and sub-microsecond electrical breakdown of water stressed to high voltages is analyzed, and several relevant models are constructed for quantitative analysis. A bubble-based, drift-diffusion (DD) model proposed here includes almost all the important physical process of the system, and successfully explains many important features routinely observed in sub-microsecond water electrical breakdown. Here many physical properties and response characteristics typical for high-field stressing of liquid water have been analyzed through numerical calculations. The internal temperature profile in the water system has been calculated by Finite Difference Time Domain (FDTD) method to probe possible heating and …
