CFDRC scientists and engineers are leaders in modeling and designing
processes for synthesis of mirco/nano scale materials. These processes
include particle nucleation and growth in spray pyrolysis and thermal
plasma synthesis techniques, low pressure plasma techniques or atmospheric
nucleation. The simulation and analysis tools can account for formation,
transport, dispersion, and deposition of nanoparticles in a variety
of applications under the influence of various effects, such as
aerodynamic forces, turbulence, electric field, thermophoresis,
and Brownian motion.
Physical Models
CFDRC uses Eulerian and Lagrangian computational methods for modeling
particle behavior and dynamics coupled with:
- Complex environments under different force fields
- Reaction paths and mechanism for aerosol nucleation
- Homogeneous and heterogeneous nucleation of nanoparticles
- Growth of particles from condensation and coagulation
- The effects of flow, heat transfer, and species conservation
