A deterministic Fokker--Planck/lattice-Boltzmann micro--macro solver for dilute Hookean polymer solutions
Xueqin Liu, Shi Shu, Yaolong Yu +3
Deterministic micro--macro simulation of polymer solutions requires the coupled evolution and spatial transport of a configuration distribution, together with the conversion of its…
Purified Two-Relaxation-Time Lattice Boltzmann Method: Removing Ghost Modes from TRT for Enhanced Stability
Yuan Yu, Yaolong Yu, Yuting Zhou +3
The two-relaxation-time (TRT) lattice Boltzmann model is widely adopted for its simplicity and tunable boundary accuracy. However, its collision operator relaxes the full symmetric…
An improved lattice Boltzmann method with a novel conservative boundary scheme for viscoelastic fluid flows
Yuan Yu, Siwei Chen, Lei Wang +2
The high Weissenberg number problem has been a persistent challenge in the numerical simulation of viscoelastic fluid flows. This paper presents an improved lattice Boltzmann metho…
Two-relaxation-time regularized lattice Boltzmann model for convection-diffusion equation with variable coefficients
Yuan Yu, Zuojian Qin, Haizhuan Yuan +1
In this paper, a new two-relaxation-time regularized (TRT-R) lattice Boltzmann (LB) model for convection-diffusion equation (CDE) with variable coefficients is proposed. Within thi…
Two-relaxation-time regularized lattice Boltzmann model for Navier-Stokes equations
Yuan Yu, Zuojian Qin, Siwei Chen +2
In this paper, we propose a novel two-relaxation-time regularized lattice Boltzmann (TRT-RLB) model for simulating weakly compressible isothermal flows. A free relaxation parameter…
