Parasitic hydrogen bubble evolution in vanadium redox flow batteries: A lattice Boltzmann study
K. Duan, T. H. Vu, T. Kadyk +3
Vanadium redox flow batteries (VRFBs) are a promising technology to capture and store energy from renewable sources, reducing the reliance on fossil fuels for energy generation. Ho…
The interplay of shape and catalyst distribution in the yield of compressible flow microreactors
G. C. Antunes, M. Jiménez-Sánchez, P. Malgaretti +2
We develop a semi-analytical model for transport in structured catalytic microreactors, where both reactant and product are compressible fluids. Making use of the lubrication and F…
A lattice Boltzmann approach for acoustic manipulation
E. Castro-Avila, P. Malgaretti, J. Harting +1
We employ a lattice Boltzmann method to compute the acoustic radiation force produced by standing waves on a compressible object. Instead of simulating the fluid mechanics equation…
Inertial focusing of a dilute suspension in pipe flow
Othmane Aouane, Marcello Sega, Bastian Bäuerlein +2
The dynamics of rigid particle suspensions in a wall-bounded laminar flow present several non-trivial and intriguing features, including particle ordering, lateral transport, and t…
Capillary interactions, aggregate formation and the rheology of particle-laden flows: a lattice Boltzmann study
Lei Yang, Marcello Sega, Steffen Leimbach +3
The agglomeration of particles caused by the formation of capillary bridges has a decisive impact on the transport properties of a variety of at a first sight very different system…
Instability of particle inertial migration in shear flow
Evgeny S. Asmolov, Tatiana V. Nizkaya, Jens Harting +1
In a shear flow particles migrate to their equilibrium positions in the microchannel. Here we demonstrate theoretically that if particles are inertial, this equilibrium can become…
Inertial migration of oblate spheroids in a plane channel
Tatiana V. Nizkaya, Anna S. Gekova, Jens Harting +2
We discuss an inertial migration of oblate spheroids in a plane channel, where steady laminar flow is generated by a pressure gradient. Our lattice Boltzmann simulations show that…
Hydrodynamic simulations of sedimenting dilute particle suspensions under repulsive DLVO interactions
David Jung, Maximilian Johannes Uttinger, Paolo Malgaretti +3
We present guidelines to estimate the effect of electrostatic repulsion in sedimenting dilute particle suspensions. Our results are based on combined Langevin dynamics and lattice…
Structure and rheology of suspensions of spherical strain-hardening capsules
Othmane Aouane, Andrea Scagliarini, Jens Harting
We investigate the rheology of strain-hardening spherical capsules, from the dilute to the concentrated regime under a confined shear flow using three-dimensional numerical simulat…
Self-Similar Liquid Lens Coalescence
Michiel A. Hack, Walter Tewes, Qingguang Xie +4
A basic feature of liquid drops is that they can merge upon contact to form a larger drop. In spite of its importance to various applications, drop coalescence on pre-wetted substr…
The effect of the liquid layer thickness on the dissolution of immersed surface droplets
Qingguang Xie, Jens Harting
Droplets on a liquid-immersed solid surface are key elements in many applications, such as high-throughput chemical analysis and droplet-templated porous materials. Such surface dr…
From dot to ring: the role of friction on the deposition pattern of a drying colloidal suspension droplet
Qingguang Xie, Jens Harting
The deposition of particles on a substrate by drying a colloidal suspension droplet is at the core of applications ranging from traditional printing on paper to printable electroni…
Diffusion dominated evaporation in multicomponent lattice Boltzmann simulations
Dennis Hessling, Qingguang Xie, Jens Harting
We present a diffusion dominated evaporation model using the popular pseudopotential multicomponent lattice Boltzmann method introduced by Shan and Chen. With an analytical computa…
Multiphase lattice Boltzmann simulations for porous media applications -- a review
Haihu Liu, Qinjun Kang, Christopher R. Leonardi +6
Over the last two decades, lattice Boltzmann methods have become an increasingly popular tool to compute the flow in complex geometries such as porous media. In addition to single…
