AbstractThe reactive spraying deposition technology is a new catalyst layer fabrication technology for producing nanometer particle and spraying the catalyst layer with steady performance. A three-dimensional comprehensive mathematical model of flow and heat/mass transfer coupling with chemical reactions for fuel gas and droplet combustion during reactive spraying deposition technology (RSDT) is presented in this paper to theoretically study complex physical and chemical processes during RSDT. The RNG k -ε model is employed to describe turbulent combustion gas flow. The droplet particle is tracked and analyzed in a Lagrangian frame. The Monte Carlo method is used to simulate the growth of surface structure of the catalyst layer. The computational results can be used to provide some reference for optimization of this technology.
