Modeling of plasma assisted formation of precipitates in zirconium containing liquid precursor droplets

This paper focuses on the modeling of heat and mass transfer in precursor containing droplets injected into a plasma jet and the estimation of precipitate formation in these droplets from the solute. A hybrid model is employed where the plasma temperature and velocity fields are obtained from previous experimental results and the heat and mass transfer around droplets are modeled. The precipitate formation zones from the zirconium acetate solution in these droplets are estimated based on the solute concentration field within the droplet. A simple homogeneous nucleation hypothesis is employed in predicting the regions of droplets where zirconia might precipitate. The effects of droplet size, injection
