Abstract: In the paper the first 200 ns of the air pulsed interelectrode discharge with gasdynamics dynamics is considered. Exactly this first step of the discharge evolution is the most interesting for obtaining the properties of heat power input in the interelectrode gap. The data about heating of layers near the cathode and the anode, volume heating at the end of the first step are presented. The spherical shock wave is produced near the cathode.

Keywords: impulse interelectrode discharge, plasma, simulation, air, thermal physics.
