“…The most investigated mixer for liquid-liquid dispersion in turbulent flow in the literature is the classical Kenics helical mixer (Middleman, 1974;Chen and Libby, 1978;Haas, 1987;Berkman andCalabrese, 1988 andYamamoto et al, 2007). Emulsification using the Sulzer SMX mixer has been studied not only in laminar flow (Legrand et al, 2001;Das et al, 2005;Liu et al, 2005;Rama Rao et al, 2007;Fradette et al, 2007;Gingras et al, 2007) but also in turbulent regime (Streiff et al, 1997). Results about liquid-liquid dispersion are also reported in the literature using the SMV mixer (Streiff, 1977;Streiff et al, 1997), the Lightnin Series 50 (Al Taweel and Walker, 1983;El Hamouz et al, 1994) and the High Efficiency Vortex mixer (Lemenand et al, 2001(Lemenand et al, , 2003(Lemenand et al, , 2005.…”

“…Although the geometry and flow conditions studied in this work are limited to a simple slit flow and a bubble/droplet that does not break, in future work, we plan to further test this boundary condition on much more complex flow situations. In particular, this boundary condition will be applied to simulate two‐phase liquid‐liquid dispersion in static mixers . Even though only the D3Q15 lattice was used in this work, we believe that since the formulation of the proposed boundary condition is quite general, the proposed approach is also suitable for common D2Q9, D3Q19, and D3Q27 lattices.…”

“…This class of periodic boundaries with pressure difference has been applied to lattice Boltzmann single‐phase simulations in the works of Zhang and Kwok and Kim and Pitsch and multiphase simulations in the work of Wang et al Wang et al applied this type of periodic pressure difference to simulate the behavior of droplets in microchannels. Also, this type of periodic pressure difference boundary conditions may find interesting applications to model immiscible two‐phase flows through periodic structures (eg, in the case of a train of static mixers). Indeed, using this type of boundary condition may reduce the number of mixing elements actually required to simulate the flow through the entire structure.…”

Summary A new pressure difference boundary condition between a pair of inlet and outlet boundaries in an immiscible multiphase periodic flow is introduced. This boundary condition is globally mass conservative and makes use of a simple proportional‐integral‐derivative controller to accurately control the pressure difference. For a droplet/bubble that crosses the outlet to reenter at the inlet of a periodic slit flow, the stability and accuracy of the boundary condition are numerically studied for a wide range of flow conditions. A visualization of a droplet crossing the outlet boundary provides qualitative evidence that the boundary condition works effectively. More importantly, quantitative results also confirm that the targeted average pressure difference is adequately set and that the total momentum in the pressure drop direction is nearly constant (which is what is expected from a perfect multiphase periodic pressure difference boundary condition). This new type of multiphase boundary condition is expected to open up new avenues to simulate complex interfacial multiphase systems using the lattice Boltzmann method.

Recent advances in the understanding of colloids has enabled the design of food products that are healthier and tastier, in line with consumer expectations. Specifically, emulsion design and hydrocolloid structuring can be used to address the issue of fat reduction in foods by allowing the production of reduced fat products that provide similar sensory attributes. Additionally, various techniques for encapsulating molecules, such as flavour, nutraceuticals or drugs, are now being developed. The application of such techniques in food products can improve micronutrient bioavailability by means of targeted and controlled delivery, increasing the nutritional value. Colloidal structures can also be designed to enhance consumer experience, mimic fat or control satiety. Such novel improvements, as well as their potential translation into commercial food products, are highlighted in this paper, which focuses primarily on the areas of emulsion technologies and hydrocolloids.
