Modelling of transport of interfacial area concentration in two-phase flow systems
Most postulated accidents in Light Water Reactors are governed by two-phase flow processes and related evaporation/condensation heat transfer, the modelling of which still presents a major theoretical challenge. A new description is presented for interfacial transport based on an explicit modelling of the interfacial area concentration and its evolution in time and space. A transport equation for the particle number density is derived and the corresponding source terms for interfacial area generation or destruction are formulated. The evolution of the interfacial area concentration is thus described as a dynamic, time dependent process and as such provides the basis for an improved description of interfacial transport processes.
