Efficient use of vectorization enables us to simulate diffusion in disordered porous media, represented by two- or three-dimensional lattices, with up to 109 sites, and a speed of nearly four steps per microsecond and per Cray-YMP processor.
In this paper, an oxidation-diffusion model was used to simulate the diffusion of alloying elements and the corresponding microstructural changes in different superalloy-coating systems at high temperature.
A simplified one-dimensional Diffusion-Sorption model with a three-zone domain was used to simulate the diffusion process by calculating the concentration profile of iodine across the adductor region, which fits well with the experiment data.
This type of equations can be used to simulate anomalous diffusion in fractal media.
This model was also used to simulate oxygen diffusion in the liquid phase.
Brownian dynamics and single particle tracking were used to simulate the diffusion process of individual molecules through a model cytoskeleton.
Monte Carlo method is often used to simulate chloride diffusion in concrete and has been verified by some experiments (Tikalsky et al. 2005).
The KMC method is used to simulate the diffusion of the point defects, and formation and dissolution of extended defects, whereas a quasi-atomistic approach is used to take into account the carrier densities.
Molecular dynamics methods were used to simulate the diffusion of noble gas molecules, Ne, Ar, and Kr, in the one-dimensional zeolite channels of VET, AFI, VFI, and MCM-41.
Finally, 3DFLUX is used to simulate advection-diffusion of a complex temperature field in an incompressible turbulent flow of practical relevance, and its results are in excellent agreement with experimental measurements.
