High-order thermodynamic nonequilibrium in three-dimensional compressible flows: Kinetic moment closure and multigradient coupling
Huilin Lai, Qinghong Guo, Yanbiao Gan +3
High-order thermodynamic nonequilibrium (TNE) in three-dimensional compressible flows reflects the breakdown of low-order kinetic moment closure in strong-gradient regions. Using C…
Stability analysis of discrete Boltzmann simulation for supersonic flows: Influencing factors, coupling mechanisms and optimization strategies
Yanhong Wu, Yanbiao Gan, Aiguo Xu +1
Supersonic flow simulations face challenges in trans-scale modeling, numerical stability, and complex field analysis due to inherent nonlinear, nonequilibrium, and multiscale chara…
Droplet coalescence kinetics: Coalescence mechanisms and thermodynamic non-equilibrium effects under isothermal and non-isothermal conditions
Guanglan Sun, Yanbiao Gan, Bin Yang +2
This study investigates the droplet coalescence mechanisms and the interplay between various thermodynamic non-equilibrium (TNE) effects under isothermal and non-isothermal conditi…
Thermodynamic nonequilibrium effects in three-dimensional high-speed compressible flows: Multiscale modeling and simulation via the discrete Boltzmann method
Qinghong Guo, Yanbiao Gan, Bin Yang +3
Three-dimensional (3D) high-speed compressible flow is a typical nonlinear, nonequilibrium, and multiscale complex flow. Traditional fluid mechanics models, based on the quasi-cont…
Multiscale thermodynamic nonequilibrium effects in Kelvin-Helmholtz instability and their relative importance
Zhongyi He, Yanbiao Gan, Bin Yang +3
