- Abstract
A three-dimensional stochastic simulation was developed to simulate growing process of particles deposit on a single fiber in Kuwarbara cell due to the collection mechanisms from inertial impaction and interception. The distributions of size of particle dendrites were calculated to quantificationally describe the complex deposit morphologies. The results indicate that the deposition morphologies strongly depend on Stokes number and interception parameter. A small stokes number tends to give a fewer but larger particle dendrites with a more open and loose structure, whereas a greater stokes number leads to a compact structure. The interception parameter shows different influencing degree to deposition morphology at different Stokes numbers. In the case of low Stokes number, there is no significant difference in heights of particle dendrites between various interception parameters, whereas for high Stokes number, the interception parameter plays a significant role in the morphologies transition from compact structures to dendritic. In addition, a larger interception parameter may weaken the effect of particle inertia on formation and growth of particle dendrites.
