Abstract

Laser beam treatment of the surface leads to vaporization. Cooling of the vapor by the surrounded gas results in condensation and the ultrafine particles creation. To make clear conditions of the particles formation, a two-phase hydrodynamic flow of the erosion torch was simulated. A case of the free laminar vapor jet inside the inert gas atmosphere was investigated. The particles are founded to create inside a thin layer -- the condensation front. The particle dimension is proportional to the second power of the ambient gas pressure.
