On the characteristic length scale for the synthetic turbulence based on the Spalart-Allmaras model
Qilong Guo, Pengxin Liu, Chen Li +2
In the hybrid RANS-LES simulations, proper turbulent fluctuations should be added at the RANS-to-LES interface to drive the numerical solution restoring to a physically resolved tu…
Analysis of Wall Heat Flux of a Hypersonic Shock Wave / Boundary Layer Interaction with a Novel Decomposition Formula
Xiaodong Liu, Chen Li, Pengxin Liu +3
The generation mechanism of wall heat flux is one of the fundamental problems in supersonic/hypersonic turbulent boundary layers. A novel heat decomposition formula under the curvi…
Decomposition Formula for the Wall Heat Flux of a Compressible Boundary Layer
Dong Sun, Qilong Guo, Xianxu Yuan +3
Understanding the generation mechanism of the heating flux is essential for the design of hypersonic vehicles. We proposed a novel formula to decompose the heat flux coefficient in…
Hybridizing WENO implementations of interpolation and reconstruction-wise operation for upwind-biased schemes with free-stream preservation
Qin Li, Dong Sun
Cases have shown that WENO schemes usually behave robustly on problems containing shocks with high pressure ratios when uniformed or smooth grids are present, while nonlinear schem…
WENO interpolation-based and upwind-biased schemes with free-stream preservation
Qin Li, Dong Sun
Based on the understandings regarding linear upwind schemes with flux splitting to achieve free-stream preservation (Q. Li, etc. Commun. Comput. Phys., 22 (2017) 64-94), a series o…
On free-stream preservation in stationary grids for arbitrary linear upwind schemes
Qin Li, Dong Sun, Hanxin Zhang
In order to improve the application maturity of high-order difference schemes, the free-stream preservation property, whose importance has been widely recognized in recent years, h…
Efficient and Long-Time Accurate Second-Order Methods for Stokes-Darcy System
Wenbin Chen, Max Gunzburger, Dong Sun +1
We propose and study two second-order in time implicit-explicit (IMEX) methods for the coupled Stokes-Darcy system that governs flows in karst aquifers. The first is a combination…
