Abstract :
The paper presents a two-dimensional hydrodynamic model of a high-current vacuum arc. The main areas of interest of this numerical modeling are arc column and anode areas. Homogeneous current density and ion flows from the cathode region are assumed. The results of numerical calculations of current and ions flow to the anode in dependence of discharge gap and total current are given and a possible scenario for the transition from the diffuse to the anode-spot mode is discussed
