Reactive bubble columns are omnipresent in the chemical industry. The layout of these columns is still limited by correlations and therefore improved simulation techniques are required to describe the complex hydrodynamics/reaction interaction. In th

This study presents numerical investigations of air–water two-phase flows for upward flow in a vertical helical pipe. The numerical simulations were done in accordance with the experimental work of...

Abstract Flow mixing of two miscible liquids with the addition of gas bubbles is a process often found in industrial chemical apparatus for the production of primary matter. The ongoing optimization of such processes also involves the transformation

This study reports numerical results for the flow of two initially perfectly mixed but immiscible liquids in helical and straight pipes, with a view toward optimal separation. Different flow orientations were considered, horizontal, upward, and downw

This work documents optimal flow conditions in terms of Reynolds number Re (and Dean number De) for mixing of two miscible liquids in helical pipes. Extending our previous investigations (Mansour et al., 2017, 2018), many more configurations have bee

This work considers numerical investigations of liquid–liquid mixing in helical pipes and coiled flow inverters (CFI). Since mixing is particularly efficient in the developing region, a higher mixing efficiency is obtained by inverting the flow dir

The objective of this study is to identify a chemical marker combination that can be measured by Laser-Induced Fluorescence and used for predicting the heat release rate distribution in premixed methane-air flames at various equivalence ratios. Direc
