FiFi: Simulation of Dendrite Formation of Aerosol Particles on a Single Fibre

På svenska

Author

Summary, in English

A personal computer program, FiFi, that makes a real-time, two-dimensional simulation of the dynamic deposition process of particles on a single fibre, has been developed. The formation of dendrites and the particle transport as a function of different parameters are simulated. The trajectory of a spherical particle as a function of external forces and diffusion is calculated by integration and the particle moves across the display until it is captured or passes the fibre. The particles are captured directly on the fibre or on previously captured particles and form dendrites. A particle is characterised by five basic parameters which can be changed in various ways. The size and charge of the fibre are also parameters. At this state the flow around the fibre is described by either of three different air flow models, and four different electric fields can be simulated. The efficiency of any fibre-dendrite geometry can be calculated.
