Research and educational computer program of breakdown initiation in liquids

Computer program 'Bubbreak' is designed with two purposes: educational and research. It consists of three parts: computation of prebreakdown time duration t(E, P, T, r0) according to bubble model of breakdown initiation, graphic simulation of prebreakdown processes in gap with the visualization of bubbles on electrodes, mathematical treatment of t(E, P, T, r0) to get E(t)|P,T,r, E(P)|t,T,r, t(E)|P,T,r, t(P)|E,T,r, E(T)|P,E,r, t(r0)|P,T,E. It is assumed that in every dependency other parameters is fixed, but can be changed with the help of special data window. Here E - electrical field intensity, P - outer pressure, T - temperature, r0 - radius of most 'dangerous bubble' that is on electrode. The liquid for treatment can be chosen from library. For the new dielectric liquid it is necessary to input it's physical properties: dielectric permittivity Ε, vapor pressure Ps(T), viscosity η(T), surface tension σ. With the help of dialog windows one can choose required dependency and it's physical parameters. Only one model's parameters critical field strength it should to input. Default it is 10 MV/cm.
