Simulation of heat and mass transfers inside a nanopowders synthesis reactor
Résumé
Recently the research about technical ceramics knows a rehabilitated interest. Work concentrates on the development of the intrinsic properties of these materials for their use in various fields of industry (mechanical, thermal, ...). The synthesis processes of nanopowder play a significant role in the production of such materials. This work focuses more particularly in the synthesis of the nanopowder by laser pyrolysis, base on a tree-dimensional numerical model developed in order to understand the influence of different heat transfers both globally and locally around the reaction zone. The mathematical model is based on Navier-Stokes, energy and species equations. The numerical approximation is based on unstructured finite volume approximation used by CFX industrial CFD tools.
