We propose an improvement of an analytical approach presented previously for determining the surface shape formed during laser cladding process at the goods manufacturing in additive technologies. The approach is based on the balance of pressures on

Two-phase gas-powder flow modeling for a triple coaxial nozzle were carried out, based on equations of viscous gas dynamics and the SST-model of turbulence. Particles trajectories were calculated using of the Lagrangian approach simultaneously for al
