Adaptive Simulation of Electrical Discharges
We present an adaptive animation method for electrical discharges. Electric discharges can be simulated using the dielectric breakdown model. Regular discretization of the governing Laplace equation leads to huge equation systems, and the computational cost of solving the equations quickly becomes prohibitive at high resolutions, especially for simulations in 3D. In contrast, our method discret...

متن کاملElectrical characterization of radio frequency discharges
Two electrical techniques that are frequently used to characterize radio frequency plasmas are described: current–voltage probes for plasma power input and compensated Langmuir probes for electron energy probability functions and other parameters. The following examples of the use of these techniques, sometimes in conjunction with other diagnostic methods, are presented: plasma source standardi...
متن کاملOn the NOx production by laboratory electrical discharges and lightning
Different approaches are used in estimating the global production of NOx by lightning flashes, including field measurements carried out during thunderstorm conditions, theoretical studies combining the physics and chemistry of the electrical discharges, and measurements of NOx yield in laboratory sparks with subsequent extrapolation to lightning. In the latter procedure, laboratory data are ext...
متن کاملMyocardium tissue changes caused by electrical transthoracic discharges in rats
BACKGROUND Cardiomyocytes cytoarchitecture changes caused by transthoracic countershocks have been focused recently. We aimed to evaluate the effects of electrical discharge application in the mitochondria structure in atrial myocardium of rats. METHODS An electrical cardioverter was adapted to small rodent animals for our research. Electrical discharges were applied to the precordial region ...
