Non-stationary conjugate heat exchange and phase transition at the high-energy surface processing. Part 1. Computational approach and its realization

Non-stationary conjugate heat exchange and phase transition at the high-energy surface... Abstract The paper presents the developed physical and mathematical models, calculation procedure based on finite-element method, and also the software for the numerical studying the processes of the non-stationary conjugate heat exchange and phase transition during the surface processing with high-concentrated energy fluxes with stationary, pulse, and movable heat sources (fusing of coatings, surface layer quenching, surface cleaning, etc.). The proposed and realized method permits to study the processes within a wide range of the power density of external heat fluxes q∈[107; 1014] W/m2 with significantly different spatial and temporal scales. The results presented are of interest for understanding and simulation of the processes occurring at the surface processing of the coatings and materials with high-concentrated energy fluxes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Abstract The paper presents the developed physical and mathematical models, calculation procedure based on finite-element method, and also the software for the numerical studying the processes of the non-stationary conjugate heat exchange and phase transition during the surface processing with high-concentrated energy fluxes with stationary, pulse, and movable heat sources (fusing of coatings, surface layer quenching, surface cleaning, etc.). The proposed and realized method permits to study the processes within a wide range of the power density of external heat fluxes q∈[107; 1014] W/m2 with significantly different spatial and temporal scales. The results presented are of interest for understanding and simulation of the processes occurring at the surface processing of the coatings and materials with high-concentrated energy fluxes.
