Spurious currents suppression by accurate difference schemes in multiphase lattice Boltzmann method
Zhangrong Qin, Wenbo Chen, Chunyan Qin +2
Spurious currents, which are often observed near a curved interface in the multiphase simulations by diffuse interface methods, are unphysical phenomena and usually damage the comp…
Chemical-potential Multiphase Lattice Boltzmann Method with Superlarge Density Ratios
Binghai Wen, Liang Zhao, Wen Qiu +2
The liquid-gas density ratio is a key property of multiphase flow methods to model real fluid systems. Here, a chemical-potential multiphase lattice Boltzmann method is constructed…
A pseudopotential multiphase lattice Boltzmann model based on high-order difference
Zhangrong Qin, Wanling Zhao, Yanyan Chen +2
The hyperbolic tangent function is usually used as a reliable approximation of the equilibrium density distributions of a system with phase transitions. However, analyzing the accu…
The roles of wettability and surface tension in droplet formation during inkjet printing
Bing He, Sucui Yang, Zhangrong Qin +2
This paper describes a lattice Boltzmann-based binary fluid model for inkjet printing. In this model, a time-dependent driving force is applied to actuate the droplet ejection. As…
