Process design, especially in the chemical industry, often requires a detailed understanding and accurate quantification of interfacial mass transfer. Experimental investigations, however, are often infeasible as required measurement quantities and locations are inaccessible. Thus, Direct Numerical Simulations (DNS) have become a viable tool for the detailed study of mass transfer processes. This paper presents a numerical modelling framework for the simulation of dilute species transfer based on an algebraic Volume-of Fluid method, aiming at the deduction of an improved closure model for interfacial species transfer from single rising bubbles. To this end, the Continuous Species Transfer (CST) model [18] and state-of-the-art high performance computing techniques are employed. (C) 2018 Elsevier Ltd. All rights reserved.
