A scale-based study of the Reynolds number scaling for the near-wall streamwise turbulence intensity in wall turbulence
Cheng Cheng, Lin Fu
Very recently, a defect model which depicts the growth tendency of the near-wall peak of the streamwise turbulence intensity has been developed (Chen Sreenivasan, J. Fluid Mec…

Large-scale motions and self-similar structures in compressible turbulent channel flows
Cheng Cheng, Lin Fu
In this work, we study the scale characteristics of the log- and outer-region motions and structures in subsonic and supersonic turbulence. To this end, a series of direct numerica…

Streamwise inclination angle of wall-attached eddies in turbulent channel flows
Cheng Cheng, Wei Shyy, Lin Fu
We develop a new methodology to assess the streamwise inclination angles (SIAs) of the wall-attached eddies populating the logarithmic region with a given wall-normal height. To re…
