Measuring the maximum size of a particle which passes through wire cloth is important for evaluating the performance of its filtration. Although the Dutch Weave is a popular structure of wire cloth, it requires a special equipment to measure the size of spaces between wires since its structure is so complicated that optical measurement is not applicable. In this paper, we first propose a method for calculating the size analytically. Then we propose a new method which employs a physical simulation which runs on a PC based on the dynamics of rigid bodies to estimate the performance of filtration of a wire cloth. The wire cloth is represented with polygonal-mesh models, and the particles are represented with spherical models. The performance is presented as the maximum size of a sphere which passes through the polygonal-mesh models. The obtained values showed the proposed approach is applicable for estimating the performance of filtration. As our method is based on a physical simulation, it is possible to apply to non-existing wire cloths. This would be useful for developing new products.
