Abstract : In this work, are presented the results of a model coupling both dynamic and thermal histories of a single zirconia particle injected into a d.c plasma jet. The model developed calculates the heat transfer and phase changes within the particle along its trajectory. It is based on the Stefan problem with an explicit determination of the position of the interface solid-liquid. The evaporation is described according to the approach -Back pressure- The model is adapted to the calculation of thermal and dynamic behaviors of agglomerated particles.

Keywords : fast modelling d.c plasma spray agglomerated zirconia particle thermal history
