TY - JOUR A2 - Fillon, Michel AU - Scaraggi, Michele AU - Carbone, Giuseppe PY - 2012 DA - 2012/11/19 TI - A Two-Scale Approach for Lubricated Soft-Contact Modeling: An Application to Lip-Seal Geometry SP - 412190 VL - 2012 AB - We consider the case of soft contacts in mixed lubrication conditions. We develop a novel, twoscales contact algorithm in which the fluid- and asperity-asperity interactions are modeled within a deterministic or statistic scheme depending on the length scale at which those interactions are observed. In particular, the effects of large-scale roughness are deterministically calculated, whereasthose of small-scale roughness are included by solving the corresponding homogenized problem. The contact scheme is then applied to the modeling of dynamic seals. The main advantage of the approach is the tunable compromise between the high-computingdemanding characteristics of deterministic calculations and the much lower computing requirements of the homogenized solutions.
