| This paper presents a VOF-based approach for the numerical simulation
of non-reactive or reactive mass transfer from a rising bubble into the ambient
liquid. The mathematical model and the numerical method allow for different
solubilities of the species in the respective fluid phases, while volume changes due
to mass transfer are neglected. The discontinuity of the transfer species
concentration at the interface is modeled by means of Henry’s law. Simulations
are carried out with an extended version of the highly parallelized code FS3D,
which employs an advanced Volume-Of-Fluid (VOF) method. To analyze
complex reaction schemes a local selectivity is introduced. First numerical results
demonstrate the potential of the method for contributing to process intensification
of gas-liquid reactors. | English |
