Öttinger ETH Zürich, Department of Materials, Institute of Polymers, HCI H 543, CH-8093 Zürich, Switzerland While the field equations for complex fluids are usually formulated such that they respect the principles of nonequilibrium thermodynamics, the choice of appropriate boundary conditions is often considered as a purely mathematical problem. We here emphasize that also the formulation of boundary conditions should be guided by thermodynamics. The GENERIC framework is generalized to systems consisting of coupled 3-d bulk and 2-d boundary variables. The ideas and concepts are illustrated for two examples: (i) bulk and surface diffusion phenomena for a dilute suspension of Brownian particles, and (ii) velocity slip of entangled polymer melts at solid walls. © IWNET 2006
