Abstract EN

In this paper a detailed derivation of the general transport equations for two-phase systems using a method based on nonlocal volume averaging is presented.

The local volume averaging equations are commonly applied in nuclear reactor system for optimal design and safe operation.

Unfortunately, these equations are limited to length-scale restriction and according with the theory of the averaging volume method, these fail in transition of the flow patterns and boundaries between two-phase flow and solid, which produce rapid changes in the physical properties and void fraction.

The non-local volume averaging equations derived in this work contain new terms related with non-local transport effects due to accumulation, convection diffusion and transport properties for two-phase flow; for instance, they can be applied in the boundary between a two-phase flow and a solid phase, or in the boundary of the transition region of two-phase flows where the local volume averaging equations fail.
