ABSTRACT:
Flame-based nano-material synthesis and device fabrication processes are promising directions for developing emerging technologies. Complimentary computational and experimental approaches enable the full potential of this process to be realized. In this talk, a flame-assisted chemical vapor deposition process with applications to nano-material synthesis, nano-material based device design and improved fabrication processes will be discussed. Multi-phase reacting flow computations of the flame-based process will be presented along with complimentary experimental results. An efficient yet powerful pseudo 1D simulation for stagnation flames will be presented along with applications to carbon, titanium oxide and manganese nanoparticle formation. Expansion into 2D flame simulations will be addressed to discuss the treatment of flow perturbations that exist during experimental sampling of flame aerosols. Finally, the potential for implementing sequential flame-based steps in a continuous process for battery electrode fabrication will be explored in terms of a proposed sintering model for a growing film.
