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…
Treatment of Wall Boundary Conditions in High-Order Compact Gas-Kinetic Schemes
Jiawang Zhang, Xing Ji, Kun Xu
The boundary layer represents a fundamental structure in fluid dynamics, where accurate boundary discretization significantly enhances computational efficiency. This paper presents…
A Memory Reduction Compact Gas Kinetic Scheme on 3D Unstructured Meshes
Hongyu Liu, Xing Ji, Yunpeng Mao +2
This paper introduces a memory-reduction third-order compact gas-kinetic scheme (CGKS) for solving compressible Euler and Navier-Stokes equations on 3D unstructured meshes. The sch…
Comparison of the high-order Runge-Kutta discontinuous Galerkin method and gas-kinetic scheme for inviscid compressible flow simulations
Yixiao Wang, Xing Ji, Gang Chen +1
The Runge--Kutta discontinuous Galerkin (RKDG) method is a high-order technique for addressing hyperbolic conservation laws, which has been refined over recent decades and is effec…
