Phase separation in thermal systems: LB study and morphological characterization
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +1
We investigate thermal and isothermal symmetric liquid-vapor separations via a FFT-Thermal Lattice Boltzmann (FFT-TLB) model. Structure factor, domain size and Minkowski functional…
FFT-LB modeling of thermal liquid-vapor systems
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +1
We further develop a thermal LB model for multiphase flows. In the improved model, we propose to use the FFT scheme to calculate both the convection term and external force term. T…
Lattice Boltzmann study on Kelvin-Helmholtz instability: the roles of velocity and density gradients
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +1
A two-dimensional lattice Boltzmann model with 19 discrete velocities for compressible Euler equations is proposed (D2V19-LBM). The fifth-order Weighted Essentially Non-Oscillatory…
Multiple-Relaxation-Time Lattice Boltzmann Approach to Compressible Flows with Flexible Specific-Heat Ratio and Prandtl Number
Feng Chen, Aiguo Xu, Guangcai Zhang +2
A new multiple-relaxation-time lattice Boltzmann scheme for compressible flows with arbitrary specific heat ratio and Prandtl number is presented. In the new scheme, which is based…
Shock Wave Response of Porous Materials: From Plasticity to Elasticity
Aiguo Xu, Guangcai Zhang, Yangjun Ying +2
Shock wave reaction results in various characteristic regimes in porous material. The geometrical and topological properties of these regimes are highly concerned in practical appl…
Control spiral wave dynamics using feedback signals from line detectors
Guoyong Yuan, Aiguo Xu, Guangrui Wang +1
We numerically study trajectories of spiral-wave-cores in excitable systems modulated proportionally to the integral of the activity on the straight line, several or dozens of equi…
