Dynamic behavior of interfaces: Modeling with nonequilibrium thermodynamics

摘要: In multiphase systems the transfer of mass, heat, and momentum, both along across phase interfaces, has an important impact on overall dynamics system. Familiar examples are effects surface diffusion foam drainage (Marangoni effect), or effect elasticities deformation vesicles red blood cells in arterial flow. this paper we will review recent work modeling processes associated with interfaces context nonequilibrium thermodynamics (NET). The focus be NET frameworks employing Gibbs dividing model, which interface is modeled as a two-dimensional plane. This plane excess variables it, such mass density, momentum energy entropy density. We number can used to derive balance equations constitutive models for time rate change these variables, result in-plane (tangential) processes, exchange adjoining bulk phases. These must solved together balances phases, set boundary conditions coupling equations. entire constitutes comprehensive continuum model system, allows us examine role interfacial With respect primarily extra stress tensor.
