Abstract

Modelling of the supersonic compressible plasma flow has been developed to describe the thermodynamic and transport properties of the plasma spray physical vapor deposition process (PS-PVD) for typical processing parameters used for columns microstructure formation of thermal barrier coating (TBC). Commercial computational fluid dynamics software (ANSYS fluent 16.1) has been used for the simulations. The required properties of the plasma gas mixtures were obtained as a function of temperature and pressure from the thermodynamic calculations in chemical equilibrium (CEA program) with the effect of ionization. The carrier gas effects on the plasma fluid field was discussed. The boundary layer thickness was calculated near the sample wall. Two-dimensional Monte Carlo simulations have been conducted to provide insight on the evolution of PS-PVD columns. This model was implemented on a molecular scale that incorporates the effect of self-shadowing and vapor incidence angle.
