Local bubble size distributions in agitated vessels

Prediction of drop sizes for liquid–liquid systems in stirred slim reactors—Part I: Single stage impellers

“…Using this technique, drop size distributions for all phase fractions, even under transient conditions, can be determined with high time resolution. The drop size distribution was found independent of local position due to the high volume streams within the vessel, as opposed to gas/liquid systems analyzed by Laakkonen et al [31]. The high volume streams ensure the same drop size distribution at every place in the vessel.…”

The influence of temperature on the foaming of milk

“…The smaller average bubble size of foams formed from whole milk could be due to the higher viscosity of this milk when compared to skim milk. Higher viscosity promotes smaller bubble size, due to decreased rates of coalescence (Laakkonen, Moilanen, & Aittamaa, 2005).…”

The Effect of Temperature and Impeller Speed on Mechanically Induced Gas Flotation (IGF) Performance in Separation of Oil from Oilfield-Produced Water

“…Bubble behavior is one of the most important parameters in the performance of flotation cells and many researchers have focused on its role, especially in recent years in which advanced instrumentations and analyzers for bubble investigation have been introduced (Gorain et al, 1997;Wang et al, 2001;Ghosh, 2004;Laakkonen et al, 2005;Schwarz and Alexander, 2006). However, although a significant amount of work has already been done on bubble coalescence, its mechanism is still not completely understood even for pure liquids (Craig, 2004;Grau and Heiskanen, 2005).…”
