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-…
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…
Performance evaluation of high-order compact and second-order gas-kinetic schemes in compressible flow simulations
Yaqing Yang, Fengxiang Zhao, Kun Xu
The trade-off among accuracy, robustness, and computational cost remains a key challenge in simulating complex flows. Second-order schemes are computationally efficient but lack th…
An effective implementation of high-order compact gas-kinetic scheme on structured meshes for compressible flows
Yaqing Yang, Fengxiang Zhao, Kun Xu
A novel fifth-order compact gas-kinetic scheme is developed for high-resolution simulation of compressible flows on structured meshes. Its accuracy relies on a new multidimensional…
