- 2018Droplet size prediction in ultrasonic nebulization for non-oxide ceramic powder synthesiscitations
- 2017On the Validity of Continuum Computational Fluid Dynamics Approach Under Very Low-Pressure Plasma Spray Conditions ; Plasma spray physical vapor deposition aims tosubstantially evaporate powders in order to produce coatingswith various microstructures. This is achieved bypowder vapor condensation onto the substrate and/or bydeposition of fine melted powder particles and nanoclusters.The deposition process typically operates at pressuresranging between 10 and 200 Pa. In addition to the experimentalworks, numerical simulations are performed tobetter understand the process and optimize the experimentalconditions. However, the combination of hightemperatures and low pressure with shock waves initiatedby supersonic expansion of the hot gas in the low-pressuremedium makes doubtful the applicability of the continuumapproach for the simulation of such a process. This workinvestigates (1) effects of the pressure dependence ofthermodynamic and transport properties on computationalfluid dynamics (CFD) predictions and (2) the validity of thecontinuum approach for thermal plasma flow simulationunder very low-pressure conditions. The study comparesthe flow fields predicted with a continuum approach usingCFD software with those obtained by a kinetic-basedapproach using a direct simulation Monte Carlo method(DSMC). It also shows how the presence of high gradientscan contribute to prediction errors for typical PS-PVDconditions.citations
