DNS of hydrodynamics and mass transfer in gravity-driven bubbles in a vertical pipe, using the multi-marker Unstructured Conservative Level Set (UCLS) method.
The objective of these simulations is to develop correlations for the drag force coefficient, interfacial area and Sherwood number in bubbles, taking into account the confinement ratio.
