This work proposes an alternative methodology to scale-up a tube-in-tube gas–liquid contacting membrane module by developing a full-scale multi-membrane module. A novel hybrid CFD-analytical model, previously developed to predict mass transfer coefficients and bubble dispersion of a bubbly flow in a tube-in-tube membrane module, is used to simulate the gas bubble dispersion into the water and predict the ozone-water mass transfer coefficient, the interfacial area and gas holdup of the concept membrane contacting module.

This study introduces a new surrogate model to predict the distribution of species associated with a two-component single-phase flow in micro/meso-structured NETmix static mixers, aiming to find injection schemes which requires the least amount of NETmix rows to achieve a homogeneous state, thereby enabling a reduction in manufacturing costs. The NETmix’s unit cells were embedded into a lattice framework, through which the concepts of entropy and dynamic entropy were calculated by the evaluation of mass balance equations.
