A difference-free conservative phase-field lattice Boltzmann method
Chunheng Zhao, Saumil Patel, Taehun Lee
We propose an innovative difference-free scheme that combines the one-fluid lattice Boltzmann method (lBM) with the conservative phase-field (CPF) lBM to effectively solve large-sc…

Spreading and engulfment of a viscoelastic film onto a Newtonian droplet
Chunheng Zhao, Taehun Lee, Andreas Carlson
We use the conservative phase-field lattice Boltzmann method to investigate the dynamics when a Newtonian droplet comes in contact with an immiscible viscoelastic liquid film. The…

On the uniqueness of energy-minimizing curves in constrained spaces
Ki-Ahm Lee, Taehun Lee
In this paper, we investigate energy-minimizing curves with fixed endpoints and in a constrained space. We prove that when one of the endpoints, say , is fixed, the set…
