| Abstract Coupled interphase heat and mass transfer in multicomponent vapour-liquid flows is important in a wide variety of industrial processes. Efficiency improvements often require expensive pilot-scale testing and/or computer modeling, with empirical correlations derived from similar systems to determine heat and mass transfer rates. An alternative approach is to directly simulate the location of the vapour-liquid interface as well as the interphase heat and mass transfer rates. This investigation presents a Volume-of-Fluid (VOF) method for the direct numerical simulation of interface dynamics and simultaneous interphase heat and mass transfer in systems with multiple phase changing chemical species. The approach is an extension of a previously published method (Haelssig et al., Int. J. Heat Mass Transfer (2010), doi: 10.1016/j.ijheatmasstransfer.2010.05.013). The method incorporates the full interface species and energy jump conditions for coupled vapour-liquid interphase heat and mass transfer. It was validated for the ethanol-water system for the cases of wetted-wall vapour-liquid contacting and vapour flow over a smooth, stationary liquid. Good agreement was observed between empirical correlations, experimental data and numerical predictions for vapour and liquid phase mass transfer coefficients as well as vapour and liquid phase species mass fraction and temperature profiles. |
