Kurzbeschreibung (Abstract)
In this paper two variants of a VOF-based approach for the numerical simulation of the molar mass transport of a diluted species in two-phase flows with deformable interfaces are introduced and compared.
The variants differ in the manner of the computation of the mass transfer flux across the interface.
The method assumes local thermodynamical equilibrium at the interface and enables the simulation of conjugated mass transfer problems across deformable interfaces, where the mass transport resistance lies in both phases.
The considered model also allows for arbitrary distribution coefficients.
First numerical simulations show the potential and the present limits of this method.
