Abstract: Abstract Drag force plays important roles in the prediction of gas-liquid flow in stirred tanks, but systematic studies on drag models are still lacking. In this study, we evaluated the effect of four different drag… read more here.

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.

Abstract: Abstract One of the key issues with the application of drag models for non-spherical particles is the incorporation of differently shaped particles. Under real world conditions, every single grain in a powder or granule has… read more here.
