In the present work, a numerical model was developed for the simulation of the process of ceramic powder synthesis by the laser pyrolysis. It takes into account the flow, heat transfer and chemical reactions. The aim of this investigation is to develop a three dimensional model of the reactor and to characterize the influence of the various involved thermal parameters during the process. This will contribute to an improved fundamental understanding of the heat and mass transfer and fluid flow during the synthesis of ceramic nanopowdera. In addition, The reactor is studied under turbulent flow regime in order to provide first guidance of the design and the optimisation of the geometry of an industrial synthesis reactor.
