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…
Contact angle measurement on curved wetting surface in multiphase lattice Boltzmann method
Yangsha Liu, Yichen Yao, Quanying Li +1
Contact angle is an essential physical quantity that characterizes the wettability of a substrate. Although it is widely used in the studies of surface wetting, capillary phenomena…
Numerical simulation of pulmonary airway reopening by the EOS-based multiphase lattice Boltzmann method
Bing He, Chunyan Qin, Wenbo Chen +1
The aerosol formation is associated with the rupture of the liquid plug during the pulmonary airway reopening. The fluid dynamics of this process is difficult to predict because th…
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…
