The investigation of heat and mass transfer in nanopowder synthesis reactor

摘要

Rrecently the research about technical ceramics knows a renewed interest. Work concentrates on the improvement of the intrinsic properties of these materials for their use in various fields of industry (mechanical, thermal...). The synthesis processes of nanopowders play a significant role in the production of such materials. This work, focus more particularly in the synthesis of the nanopowders by laser pyrolysis, we develops a numerical model in order to understand the influence of the heat transfers accruing in the reactor and around the reaction zone, for a better description of the synthesis processes.
