Inter-compartment interaction in multi-impeller mixing: Part II. Experiments, sliding mesh and large Eddy simulations

Steady state multiple reference frame-RANS (MRF-RANS) simulations frequently show strong over-predictions of the mixing time in single-phase, multi-impeller mixing tanks, which is sometimes patched by ad hoc tuning of the turbulent Schmidt-number. In Part I of this work, we experimentally revealed the presence of macro-instabilities in the...

Inter-compartment interaction in multi-impeller mixing: Part I. Experiments and multiple reference frame CFD

CFD simulations of mixing in single-phase multi-Rushton stirred tanks based on the RANS methodology frequently show an over-prediction of the mixing time. This hints at an under-prediction of the mass exchange between the compartments formed around the individual impellers. Some studies recommend tuning the turbulent Schmidt number to address...

Identification and evaluation of CCS sweet spots in the West Netherlands Basin

Carbon Capture and Sequestration (CCS) is expected to become a serious CO2-emission reduction technology in the Netherlands, for example in the mature West Netherlands Basin (WNB). This study aims to identify and evaluate potential CO2-storage reservoirs based on geological boundary conditions. These criteria are applied to a basin-scale...
