研究目的
Investigating the plasma–liquid precursor interactions in a plasma spray process to understand the decomposition of various liquid precursors inside a radio frequency thermal plasma.
研究成果
Interactions between three different liquid precursors and an argon plasma with and without oxygen have been studied using OES. It has been shown that observing the emission bands of diatomic molecules and correlating those observations to their predicted densities over a given temperature range is a viable way to study the physicochemical dynamics of such a complex system. The effect of the solvent and that of the precursors on the plasma temperature maps has been studied, and it was concluded that using a metal alkoxide costs more energy than a nanopowder suspension, in addition to the anticipated result that water significantly cools the plasma when compared to ethanol.
研究不足
The hypothesis of thermodynamic equilibrium is, most likely, not met, and the simulations can be used as an indication of which physical phenomena and chemical reactions are occurring. Future work will investigate higher precursor concentrations to better highlight the effect of precursor molar injection rate on plasma temperature.
