Unified gas-kinetic wave-particle methods VII: diatomic gas with rotational and vibrational nonequilibrium
Yufeng Wei, Yajun Zhu, Kun Xu
Hypersonic flow around a vehicle in near space flight is associated with multiscale non-equilibrium physics at a large variation of local Knudsen number from the leading edge highl…
Multiple solutions of nonlinear coupled constitutive relation model and its rectification in non-equilibrium flow computation
Junzhe Cao, Sha Liu, Chengwen Zhong +2
In this study, the multiple solutions of Nonlinear Coupled Constitutive Relation (NCCR) model are firstly observed and a way for identifying the physical solution is proposed. The…
A high-order compact gas-kinetic scheme in a rotating coordinate frame and on sliding mesh
Yue Zhang, Xing Ji, Kun Xu
This paper extends the high-order compact gas-kinetic scheme (CGKS) to compressible flow simulations on a rotating coordinate frame. The kinetic equation with the inclusion of cent…
High-order Compact Gas-kinetic Schemes for Three-dimensional Flow Simulation on Tetrahedral Mesh
Fengxiang Zhao, Xing Ji, Wei Shyy +1
A general framework for the development of high-order compact schemes has been proposed recently. The core steps of the schemes are composed of the following. 1). Based on a kineti…
UGKWP for three-dimensional simulation of gas-particle fluidized bed
Xiaojian Yang, Yufeng Wei, Wei Shyy +1
The gas-solid particle two-phase flow in a fluidized bed shows complex physics. Following our previous work, the multi-scale framework based on gas-kinetic scheme (GKS) and unified…
High-order Unified Gas-kinetic Scheme
Gyuha Lim, Yajun Zhu, Kun Xu
In this paper, we present a high-order unified gas-kinetic scheme (UGKS) using the weighted essentially non-oscillatory with adaptive-order (WENO-AO) method for spatial reconstruct…
