| 摘要 |
The invention relates to a computer-aided method for predicting particle uptake by a surface of an object moving in a flow current, comprising the following steps: preparing a discrete model of said object and the surrounding flow, including a projection area (21) for projecting said particles formed by a mesh of cells (23) with an identical size, and a mesh of cells (13) of said surface (11); simulating the projection of particles with a different size from said projection area (21) on the surface (11), both the density Di of projected particles and their size distribution being identical for the cell (23); obtaining for each cell (13) of said surface (11) the local uptake efficiency parameter ß by dividing the density Df of particles impacting against said cell (13) by the density Di of particles projected from the projection area (21).
