The particle dynamics of ZnO particles has been modelled by Eulerian-Eulerian multiphase
model to find the radial and axial distribution of volume fraction of ZnO particles inside the cavity. This
methodology gives a more accurate prediction of the reaction rate because of the correct volume fraction
distribution spatially. The gaseous phase consisting of argon, zinc (g) and oxygen is assumed to be
primary phase while the granular ZnO particles is assumed to be secondary phase. Separate continuity,
momentum, energy equations has been solved for each phase. The mean particle size is assumed to be 10
microns. The turbulence phenomenon of both the phases is captured separately by k-
