Predicting The Nanoparticle Diffusion using Computational Fluid Dynamics (CFD)

The modeling of flow through regular sized channels is a relatively easy task. However, when the channel size reduces to the order of micrometers and nanometers, the physics of the particle motion change. Many other factors have to be taken into consideration, such as Brownian Motion and Vander-...
