Horizontal cross-flow bubble column reactors: CFD and validation by plant scale tracer experiments

Propylene Epoxidation via Shell's SMPO Process

“…For certain configurations, the gas was predicted to mainly rise through two paths near the walls, that is, the liquid in the center of the reactor would not be effectively aerated and is predicted to suffer from ''starvation'' [20]. It was therefore hypothesized that this may be due to ''O 2 starvation'' in poorly aerated regions of the large air-oxidation reactors.…”

Hydrodynamic study of a novel membrane aerated biofilm reactor (MABR): Tracer experiments and CFD simulation

“…The use of experimental techniques (tracer experiments) combined with modern tools as the computational fluid dynamic (CFD), which is a powerful approach that provides a detailed spatial distribution of flow fields providing two or threedimensional visualization of the system (Klusener et al, 2007), might provide reliable quantitative results on hydrodynamics performance facilitating the development of integrated models (hydrodynamic-reaction kinetics) to optimize variables such as reactor design, nutrient removal and energy consumption (Glover et al, 2006;Essemiani et al, 2004).…”

CFD simulation of a novel anaerobic-anoxic reactor for biological nutrient removal: Model construction, validation and hydrodynamic analysis based on OpenFOAM®

“…The application of numerical techniques to engineering has experienced great growth in recent decades, with Computational Fluid Dynamics (CFD) being one of the approaches with the greatest impact. The use of CFD in wastewater treatment processes is growing rapidly and is being applied in the resolution of complex problems (Angeloudis et al 2016, Brannock et al 2010, Liu et al 2018, Klusener et al 2007, Wicklein et al 2016, Zhang et al 2016.…”
