Groen, J.S. (author)In this project a detailed experimental analysis was performed of the dynamic flow field in bubbly flows, with the purpose of determining local hydrodynamics and scale effects. Measurements were done in gas-liquid systems (air-water bubble columns) and in gas-solid systems (air-sand bubbing fluidized beds) of different size. Amongst others with...doctoral thesis 2004

Puiman, L. (author), Almeida Benalcazar, E.F. (author), Picioreanu, C. (author), Noorman, H.J. (author), Haringa, C. (author)In large-scale syngas fermentation, strong gradients in dissolved gas (CO, H<sub>2</sub>) concentrations are very likely to occur due to locally varying mass transfer and convection rates. Using Euler-Lagrangian CFD simulations, we analyzed these gradients in an industrial-scale external-loop gas-lift reactor (EL-GLR) for a wide range of...journal article 2023
