TI - Self-Affine Elastic Contacts: Percolation and Leakage JO - Physical review letters VL - 108 SN - 0031-9007 CY - College Park, Md. PB - APS M1 - PreJuSER-20217 SP - 244301 PY - 2012 N1 - Record converted from VDB: 12.11.2012 AB - We study fluid flow at the interfaces between elastic solids with randomly rough, self-affine surfaces. We show by numerical simulation that elastic deformation lowers the relative contact area at which contact patches percolate in comparison to traditional approaches to seals. Elastic deformation also suppresses leakage through contacts even far away from the percolation threshold. Reliable estimates for leakage can be obtained by combining Persson's contact mechanics theory with a slightly modified version of Bruggeman's effective-medium solution of the Reynolds equation.
