Abstract: |
A simple and efficient numerical model for modeling of nucleation, growth, and transport of multi-component nanoparticles is developed and verified. The approach is similar to the classical method of moments but can be applied to co-condensation of several substances. The processes of homogeneous nucleation, heterogeneous growth, and coagulations due to collisions are considered in combination with the transport of particles and reacting gases within multidimensional geometries. The model is applied to the analysis of multi-component co-condensation of TaC nanoparticles within a DC plasma reactor. The analysis allows us to investigate the process of synthesis and reach the conclusions about the importance of various physical mechanisms for the final distribution of the size and chemical composition of the particles.
