A One-Dimensional Discrete Boltzmann Model for Detonation and an Abnormal Detonation Phenomenon
Yudong Zhang, Aiguo Xu, Guangcai Zhang +1
A one-dimensional discrete Boltzmann model for detonation simulation is presented. Instead of numerical solving Navier-Stokes equations, this model obtains the information of flow…
Comparative Study on Several Criteria for Non-equilibrium Phase Separation
Yudong Zhang, Aiguo Xu, Guangcai Zhang +1
Several different kinds of criteria for non-equilibrium phase separation to discriminate the two stages, the spinnodal decompostion (SD) and domain growth (DG), are compared and fu…
Nonequilibrium and morphological characterizations of Kelvin-Helmholtz instability in compressible flows
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +3
We investigate the effects of viscosity and heat conduction on the onset and growth of Kelvin-Helmholtz instability (KHI) via an efficient discrete Boltzmann model. Technically, tw…
Entropy production in thermal phase separation: a kinetic-theory approach
Yudong Zhang, Aiguo Xu, Guangcai Zhang +3
Entropy production during the process of thermal phase-separation of multiphase flows is investigated by means of a discrete Boltzmann kinetic model. The entropy production rate is…
Comparative study of discrete Boltzmann model and Navier-Stokes
Yudong Zhang, Aiguo Xu, Guangcai Zhang
Discrete Boltzmann model (DBM) is a type of coarse-grained mesoscale kinetic model derived from the Boltzmann equation. Physically, it is roughly equivalent to a hydrodynamic model…
Discrete Boltzmann method for non-equilibrium flows: based on Shakhov model
Yudong Zhang, Aiguo Xu, Guangcai Zhang +2
A general framework for constructing discrete Boltzmann model for non-equilibrium flows based on the Shakhov model is presented. The Hermite polynomial expansion and a set of discr…
