Description
Summary:In the electrodischarge technology of materials process which use electro burst phenomenon in liquids or solids the working tool is expanding discharge channel from pulsed breakdown. Plasma channel in water is made by electrical breakdown of interelectrode gap or electro burst wire and following breakdown of burst products (vapors of water and metal) in the gap. The first approach requires high amplitudeof voltage pulse and the second one needs high amplitude of current pulse. The choice of parameters of high voltage pulse generator is usually made either by empirical experience or by evaluation results of calculation of pressure waves. Still the accuracy of calculation of pressure waves is dissatisfactory because it requires making self- consistent calculation of the equations of transient process in the discharge circuit, equations of plasma state and wave dynamics. The aim of this work is the attempt to create a model that will use self-consistent solution of system of these equations and experimental check of model data.
