Efficient Wall-Modeled High-Order Compact Gas-Kinetic Scheme for Compressible Turbulent Flows
Yaqing Yang, Fengxiang Zhao, Kun Xu
Scale-resolving simulations of wall-bounded turbulent flows remain prohibitively expensive at high Reynolds numbers, owing to the stringent near-wall resolution requirements. High-…
Finite Difference Implementation of a High-order Space-Time Coupled Compact Gas-Kinetic Scheme
Fengxiang Zhao, Yibing Chen, Kun Xu
This study presents a high-order compact finite difference gas-kinetic scheme (FD-CGKS) that introduces a novel spatial discretization strategy for the efficient implementation of…
Adaptive finite volume-particle method for free surface flows
Jiawang Zhang, Fengxiang Zhao, Kun Xu
This study proposes a novel adaptive finite volume-particle method (AFVPM) for accurate and efficient free surface flow simulations. The proposed AFVPM synergistically combines the…
A High-Order Finite Volume GENO Scheme with Implicit Time Integration for Three-Temperature Radiation Diffusion Equations
Fengxiang Zhao, Yaqing Yang, Yibing Chen +1
This study presents a high-order finite volume scheme capable of large time-step integration for three-temperature radiation diffusion (3TRD) equations, where conservation is natur…
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…
