Aerosol dynamics modeling is the task of simulating the spatial and temporal evolution of the size distribution and chemical composition of a population of particles.
Aerosol dynamics modeling is challenging because particle formation models must be developed to describe:
-formation of particles from condensable material (i.e., nucleation),
-collisions of all sizes of particles with all other particles, and
-effect of the chemical composition of the particles.
Particle size distributions may be composed of multiple, distinct, superimposed populations of particle, called modes, where each mode results from a distinct source of particles, creating a multimodal size distribution.
The effect of aerosol processes on the particle size distribution is expressed mathematically by the general dynamics equation (GDE) for aerosols.
The GDE can be solved by coupling an aerosol dynamics model with a computational fluid dynamics (CFD) solver.
The CFD solver simulates diffusion-convection processes, and the aerosol dynamics model represents the effect of processes like coagulation, condensation, and nucleation as additional source and sinks in the CFD simulation.
How about in CFD-FLUENT ? [need to know this in deep ] see Labels: CFD-FLUENT
By the way, this research-work (thesis Lasman) especially for simulate and measure (experiment) the spatial and temporal evolution of the size distribution of (aerosols particle) a population of particles not with chemical composition of a population of particles.
