“…Since its inception (Higuera & Jiménez 1989; Higuera & Succi 1989), LBM has evolved into a versatile tool for the simulation of complex flows, including but not limited to turbulent flows (Dorschner, Chikatamarla & Karlin 2016, 2017), biological flows (Falcucci et al. 2021), compressible flows (Xu & Sagaut 2013; Frapolli, Chikatamarla & Karlin 2016; Dorschner, Bösch & Karlin 2018; Lin & Luo 2018; Yang, West & Harris 2018), multiphase flows (Mazloomi, Chikatamarla & Karlin 2015, 2017; Wöhrwag et al. 2018), rarefied gas (Shan, Yuan & Chen 2006) and nanoflow (Montessori et al.…”

“…In the LBM, the kinetic evolution equation for the populations f i (x, t) follows a simple algorithm of 'stream along links c i and collide at the nodes x in discrete time t'. Since its inception (Higuera & Jiménez 1989;Higuera & Succi 1989), LBM has evolved into a versatile tool for the simulation of complex flows, including but not limited to turbulent flows (Dorschner, Chikatamarla & Karlin 2016, biological flows (Falcucci et al 2021), compressible flows (Xu & Sagaut 2013;Frapolli, Chikatamarla & Karlin 2016;Dorschner, Bösch & Karlin 2018;Lin & Luo 2018;Yang, West & Harris 2018), multiphase flows (Mazloomi, Chikatamarla & Karlin 2015Wöhrwag et al 2018), rarefied gas (Shan, Yuan & Chen 2006) and nanoflow (Montessori et al 2016;Montemore et al 2017). While the majority of the LBM development concerns single-component fluids, the case of mixtures, and especially of reactive mixtures, remains an active area of research (Yan et al 2013;Feng, Tayyab & Boivin 2018;Hosseini, Darabiha & Thévenin 2018;Lin & Luo 2018;Hosseini et al 2019Hosseini et al , 2020Tayyab et al 2020;Tayyab, Zhao & Boivin 2021).…”

Consistent lattice Boltzmann model for reactive mixtures

A new lattice Boltzmann model (LBM) for chemically reactive mixtures is presented. The approach capitalizes on the recently introduced thermodynamically consistent LBM for multicomponent mixtures of ideal gases. Similar to the non-reactive case, the present LBM features Stefan–Maxwell diffusion of chemical species and a fully on-lattice mean-field realization of the momentum and energy of the flow. Besides introducing the reaction mechanism into the kinetic equations for the species, the proposed LBM also features a new realization of the compressible flow by using a concept of extended equilibrium on a standard lattice in three dimensions. The full thermodynamic consistency of the original non-reactive multicomponent LBM enables us to extend the temperature dynamics to the reactive mixtures by merely including the enthalpy of formation in addition to the sensible energy considered previously. Furthermore, we describe in detail the boundary conditions to be used for reactive flows of practical interest. The model is validated against a direct numerical simulation of various burning regimes of a hydrogen/air mixture in a microchannel, in two and three dimensions. Excellent comparison in these demanding benchmarks indicates that the proposed LBM can be a valuable and universal model for complex reactive flows.

“…As an alternative, chemical-free anti-fouling/clogging strategy becomes highly attractive. Surface patterning, creating topological structures on membrane surfaces, can manipulate the local hydrodynamics and the corresponding foulant-surface interaction 25 – 30 . With properly designed surface structures, the flow field near the membrane surface can be controlled to inhibit the deposition and accumulation of foulants particularly micro-sized foulant particles or droplets.…”

Membrane-on-chip is of growing interest in a wide variety of high-throughput environmental and water research. Advances in membrane technology continuously provide novel materials and multi-functional structures. Yet, the incorporation of membrane into microfluidic devices remains challenging, thus limiting its versatile utilization. Herein, via micro-stereolithography 3D printing, we propose and fabricate a “fish gill” structure-integrated on-chip membrane device, which has the self-sealing attribute at structure-membrane interface without extra assembling. As a demonstration, metallic micromesh and polymeric membrane can also be easily embedded in 3D printed on-chip device to achieve anti-fouling and anti-clogging functionality for wastewater filtration. As evidenced from in-situ visualization of structure-fluid-foulant interactions during filtration process, the proposed approach successfully adopts the fish feeding mechanism, being able to “ricochet” foulant particles or droplets through hydrodynamic manipulation. When benchmarked with two common wastewater treatment scenarios, such as plastic micro-particles and emulsified oil droplets, our biomimetic filtration devices exhibit 2 ~ 3 times longer durability for high-flux filtration than devices with commercial membrane. This proposed 3D printing-on-membrane approach, elegantly bridging the fields of microfluidics and membrane science, is instrumental to many other applications in energy, sensing, analytical chemistry and biomedical engineering.

The growth and development of biological tissues and organs strongly depend on the requirements of their multiple functions. Plant veins yield efficient nutrient transport and withstand various external loads. Victoria cruziana , a tropical species of the Nymphaeaceae family of water lilies, has evolved a network of three-dimensional and rugged veins, which yields a superior load-bearing capacity. However, it remains elusive how biological and mechanical factors affect their unique vein layout. In this paper, we propose a multi-functional and large-scale topology optimization method to investigate the morphomechanics of Victoria cruziana veins, which optimizes both the structural stiffness and nutrient transport efficiency. Our results suggest that increasing the branching order of radial veins improves the efficiency of nutrient delivery, and the gradient variation of circumferential vein sizes significantly contributes to the stiffness of the leaf. In the present method, we also consider the optimization of the wall thickness and the maximum layout distance of circumferential veins. Furthermore, biomimetic leaves are fabricated by using the three-dimensional printing technique to verify our theoretical findings. This work not only gains insights into the morphomechanics of Victoria cruziana veins, but also helps the design of, for example, rib-reinforced shells, slabs and dome skeletons.
