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…

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…
