OATAO is an open access repository that collects the work of some Toulouse researchers and makes it freely available over the web where possible.

What do stirred yogurt microgels look like? Comparison of laser diffraction, 2D dynamic image analysis and 3D reconstruction

“…5 in Supplementary material). This theory has been successfully applied in several studies involving colloidal suspensions, particularly latexes, well calibrated in size and shape (Burns, Yan, Jameson, & Biggs, 1997;Lachin et al, 2017;Selomulya, Amal, Bushell, & Waite, 2001). More closely connected with the food and dairy industries, some successes have been achieved in the light scattering study of model casein and micellar casein aggregates (Chardot, Banon, Misiuwianiec, & Hardy, 2002;Panouillé, Durand, Nicolai, Larquet, & Boisset, 2005;Vétier, Banon, Chardot, & Hardy, 2003).…”

Experimental study of heat transfer coefficient in heat exchanger reactors with square millimetric zigzag channels

“…It also appears that this ratio seems to follow a bellshaped trend, with a maximal value around Rep = 1000. In laminar flow regime, hp,zigzag/hp,straight first increases with Reynolds number as the intensity and the numbers of vortices in the fluid induced by the bends increase [30,31]. Then, this ratio decreases: the effect of the bends is still positive but the enhancement ratio diminishes.…”

Estimation of characteristic coagulation time based on Brownian coagulation theory and stability ratio modeling using electrokinetic measurements

“…Mixing times observed in Taylor flow devices range from 2 to 60 s [54]. Tubular reactors in the laminar flow regime, which favors the formation of spherical aggregates, are also used [55][56][57][58][59][60]. However, the laminar flow regime typically does not provide effective mixing and a mixing device should be used before the coagulator to mix the colloidal suspension and the coagulant.…”
