VOF-based simulation of reactive mass transfer across deformable interfaces

摘要

In this paper, a Volumc-of-Fluid (VOF)-bascd approach for the Direct Numerical Simulation (DNS) of reactive mass transfer in gas-liquid flows is described. At the interface, local thermodynamic equilibrium is assumed and modelled by Henry's law. First numerical simulation results arc presented for non-reactive and reactive mass transfer from rising gas bubbles to a surrounding liquid. For the evaluation of reactive mass transfer simulations with a consecutive, competitive reaction system in the liquid, a local selectivity is employed.
