Abstract
The developed general physical-mathematical model, FEM-based calculation procedure as well as the software were in practical use to simulate the processes of the non-stationary conjugate heat exchange and phase transformations during the processing of the surface with a high-concentrated energy fluxes, with a stationary, pulsed, and movable heating sources (the processing, including the surface fusing with a quasilaminar plasma jet, transfer electric arc and impulse electron beam; cleaning of the metal substrate surfaces from an oxide layer with the aid of a cathode vacuum arc, etc). The processes of practical importance with considerably different spatial and temporal scales featuring the density of the heat fluxes power q ∈ [107; 1014] W/m2 have been studied.
