DOI: 10.1016/j.ces.2017.07.022
Abstract: Abstract We propose a systematic approach for calibrating the interphase drag models used in mesoscale CFD simulations of gas-liquid flow through packed beds. The method uses packing specific liquid holdup and pressure drop data to… read more here.

DOI: 10.1038/s41598-025-23038-3
Abstract: The accurate prediction of gas-liquid two-phase flows in industrial systems relies on the careful selection of interfacial force models, particularly the drag force, which dominates momentum transport between phases. This study numerically investigates six widely… read more here.
