Evaluation of Cubic-Spline Based Gas Kinetic Method for Simulating Compressible Turbulence
Journal of Applied Fluid Mechanics, 2019 In this work, we implement and examine a new flow reconstruction methodology using cubic-splines for inter-polations in the gas kinetic method (GKM). We compare this version of GKM with the existing WENO based interpolation method.

Development of a High-Order Accurate Hybrid Scheme Using the Central Flux and WENO Schemes
, 2005 A hybrid central-WENO scheme is proposed. The fifth order WENO-LF scheme is coupled with a central flux scheme at cell face. Two sub-schemes, the WENO-LF scheme and the central flux scheme, are switched by a weighting function.

, 2019 为对可压缩流动进行高精度高分辨率的数值模拟,基于模板的光滑度量函数,构造了新型的加权因子,在此基础上将7阶精度的WENO格式与8阶中心格式进行加权组合,构造了一种自适应低耗散的中心-WENO混合格式(H-WENO7-CD8),并采用Fourier方法对离散格式数学特性进行了理论分析。该自适应的高精度中心-WENO混合格式相比于七阶的WENO格式具有更小的耗散误差。通过对激波-密度干扰问题、Rayleigh-Taylor不稳定性问题和双Mach反射问题的数值模拟,并与WENO-JS格式的计算结果对比 ...

Tensor-Train WENO Scheme for Compressible Flows [PDF]
In this study, we introduce a tensor-train (TT) finite difference WENO method for solving compressible Euler equations. In a step-by-step manner, the tensorization of the governing equations is demonstrated.

, 2016 本文构造了一个综合性能得到改进的五阶加权基本无振荡格式(WENO),其中,利用多步加权思想提高传统WENO格式在过渡点(连接一个光滑区域和一个间断点的点)区域的逼近精度,利用局部参数代替格式中的常数参数(构造权函数时,避免分母为0的参数ε和抑制激波振荡的指数参数p)以提高光滑区域特别是含高阶临界点(低于N阶的所有导数为0)区域的精度,以及利用高阶整体光滑因子来减少格式的数值耗散。数值算例表明了新格式具有良好的整体综合性能,是复杂流场数值模拟研究的一个有效方法 ...
