N-Component Free Energy Lattice Boltzmann Method with Reduction Consistency and Global Momentum Conservation
Michael Rennick, Xitong Zhang, Tim Niklas Bingert +2
We present a free energy lattice Boltzmann model capable of simulating fluid systems with an arbitrary number of immiscible components in principle. Our method is strictly reductio…
Topology Controls the Phase Separation Dynamics of Many Component Fluid Mixtures
Michael Rennick, Xitong Zhang, Halim Kusumaatmaja
Fluid mixtures, ranging from the cellular cytoplasm to synthetic DNA nanostar systems, can spontaneously compartmentalize into many () coexisting liquid phases through liquid-li…
Modelling droplet-particle interactions on solid surfaces by coupling the lattice Boltzmann and discrete element methods
Abhinav Naga, Xitong Zhang, Junyu Yang +1
We develop a three-dimensional numerical scheme for investigating interfacial flows coupled with frictional solid particles. Our approach combines the lattice Boltzmann method (LBM…
Multiple Equilibria Enables Tunable Wetting of Droplets on Patterned Liquid Surfaces
Xitong Zhang, Hongyu Zhao, Jack R. Panter +4
Patterning solid surfaces with varying wettability is important to manage droplets in microfluidics, heat transfer and printing. Solid surface roughness poses fundamental limitatio…
