A single-stage high-order compact gas-kinetic scheme in arbitrary Lagrangian-Eulerian formulation
Yue Zhang, Xing Ji, Yibing Chen +2
This study presents the development of a compact gas-kinetic scheme using an arbitrary Lagrangian-Eulerian (ALE) formulation for structured meshes. Unlike the Eulerian formulation,…
A Three-Dimensional Two-Temperature Gas-Kinetic Scheme with Generalized Kinetic Boundary Condition for Hypersonic SBLI
Xingjian Gao, Hualin Liu, Fengxiang Zhao +1
Accurate prediction of aerothermal loads in hypersonic flows is critical yet challenging due to the coupling of Shock-Wave/Boundary-Layer Interactions (SBLI) and thermal non-equili…
The stability priority of spatial-temporal coupled compact element methods over decoupled compact element methods
Qihui Gao, Xing Ji, Zhifang Du +3
With the increasing industrial demands, two families of high-order numerical schemes are widely used within the computational fluid dynamics community. One is the method of line, w…
A Geometric Multigrid-Accelerated Compact Gas-Kinetic Scheme for Fast Convergence in High-Speed Flows on GPUs
Hongyu Liu, Xing Ji, Yuan Fu +1
Implicit methods and GPU parallelization are two distinct yet powerful strategies for accelerating high-order CFD algorithms. However, few studies have successfully integrated both…
Very High-order Compact Gas-kinetic Scheme With Discontinuity Feedback Factor
Junlei Mu, Hong Zhang, Xing Ji +3
This paper presents a robust and efficient very high-order scheme for compressible flow simulation, addressing critical limitations of existing high-order methods. The proposed sch…
An efficient and robust high-order compact ALE gas-kinetic scheme for unstructured meshes
Yibo Wang, Xing Ji, Liang Pan
For the arbitrary-Lagrangian-Eulerian (ALE) calculations, the geometric information needs to be calculated at each time step due to the movement of mesh. To achieve the high-order…
