“…However, more recently it has been employed to monitor the evolution and calculate particle size distributions of the phases of liquid-liquid dispersions consisting of mineral oils and water [29][30][31]. There is also a reference that reports on the measurement of droplet size distributions by means of a microphotographic system known as bubble-cap tray while the transesterification of Gly with methyl oleate takes place [22].…”

“…Reviews on various models from literature have been published for example by Ramkrishna , Liao and Lucas , , or Kamp et al . Higher dispersed‐phase fractions usually lead to larger droplet sizes , , . This effect is induced by an intensified coalescence rate (collision frequency) but also by the influence of turbulence damping on the breakage rate .…”

Mass transfer in stirred liquid-liquid systems with and without silica nanoparticles is investigated for the saponification of benzoyl chloride. The mass transfer area is positively affected by the nanoparticles which lead to an increase of the liquidliquid interfacial area due to droplet coalescence hindrance. However, an additional mass transfer resistance induced by particles at the liquid-liquid interface was observed for all particle concentrations, since the high occupancy diminishes the available area for mass transfer. The ratio of the two oppositional effects needs to be determined to identify suitable nanoparticle reaction systems.

“…Although all the data collected could not provide the droplet size and polydispersity, the holdup of dispersed phase should play an important role on the size determination of droplets. [33] In the present study, the prediction model of water holdup can be introduced into the calculation of drop size. In the 1970s, Karabelas [34] studied the droplets formed due to turbulence in pipes, and gave a theoretical determination of the maximum drop size (d max ) as follows:…”

In this work, the water holdup and slippage for oil and water mixture flows in horizontal, vertical, and inclined pipes have been investigated. A large group of experimental data was collected from 21 different sources covering the whole range of inclination angles from À908 to 908 to reveal the holdup characteristics and develop the drift velocity model. The results show that in horizontal flows the water holdup is dependent to the flow pattern, and yet in vertical flows the water holdup is similar to the input one and the flow direction shows a few influences on the holdup. In inclined flows, the Froude numbers are relatively independent of inclination angles when the angles are greater than 308. Therefore, the changes of water holdup in the pipe with small inclination angles are more severe than those with large inclination angles. In addition, a satisfactory agreement between predicted and experimental holdups substantiates the general validity of the proposed drift velocity correlation for oil and water flows, especially for those with large inclination angles.
