Abstract
A computer-aided method for predicting particle uptake by a surface of an object moving in a flow current. The method includes preparing a discrete model of the object and the surrounding flow, including a projection area for projecting the particles formed by a mesh of cells with an identical size, and a mesh of cells of the surface. The method also includes simulating the projection of particles with a different size from the projection area on the surface, both the density Di of projected particles and their size distribution being identical for the cell. The method further includes obtaining for each cell of the surface the local uptake efficiency parameter by dividing the density Df of particles impacting against the cell by the density Di of particles projected from the projection area.
