In the present contribution, the problem of the wear particle generation and transport is considered. It is assumed that this process can be described by the diffusion equation proposed recently by Shillor et al. First the contact problem is solved numerically for a realistic loading scenario on a generic joint geometry and the necessary source terms for the diffusion equation are obtained. Then, the diffusion in the area of the acetabulum is considered. Qualitative data on the wear particle flux to the joint space are obtained and discussed.
