Abstract :
The technological process of the powder material transport into the active zone of arc high-current discharge of vacuum plasmotron is simulated. It is expected that condensed phase does not influence on the gas flow. The both gas motion in transport tube and stream formation are calculated by direct statistical modeling method whereupon equation of the granule motion is integrated. Modeling results have shown that achievement to necessary velocity of metallic powder is allowed by the providing of the consumption of the transport gas and sufficient length of the transport tube.
