Quantifying non-equilibrium pressure-gradient turbulent boundary layers through a symmetry-based framework
Wei-Tao Bi, Ke-Xin Zheng, Jun Chen +1
This study establishes a symmetry-based framework to quantify non-equilibrium processes in complex pressure gradient (PG) turbulent boundary layers (TBLs), using a Lie-group-inform…
A symmetry-based theory for the mean velocity profiles of turbulent boundary layers subjected to pressure gradient and historical turbulence effects
Tan-Tan Du, Jun Chen, Wei-Tao Bi +1
The pressure gradient has a significant influence on the mean-flow properties of turbulent boundary layers. Conventional analytical studies on PG turbulent boundary layers are cond…
Quantifying equilibrium pressure-gradient turbulent boundary layers via a symmetry approach
Wei-Tao Bi, Jun Chen, Zhen-Su She
We propose a theory for predicting the mean velocity and Reynolds shear and normal stresses profiles in the wake region of equilibrium adverse pressure-gradient (PG, APG) turbulent…
Boundary layer structure in turbulent Rayleigh-Bénard convection in a slim box
Hong-Yue Zou, Wen-Feng Zhou, Xi Chen +3
The logarithmic law of mean temperature profile has been observed in different regions in Rayleigh-Bénard turbulence. However, how thermal plumes correlate to the log law of temper…
Predictions of canonical wall bounded turbulent flows via a modified equation
Xi Chen, Fazle Hussain, Zhen-Su She
A major challenge in computation of engineering flows is to derive and improve turbulence models built on turbulence physics. Here, we present a physics-based modified equati…
Bulk flow scaling for turbulent channel and pipe flows
Xi Chen, Fazle Hussain, Zhen-Su She
We report a theory deriving bulk flow scaling for canonical wall-bounded flows. The theory accounts for the symmetries of boundary geometry (flat plate channel versus circular pipe…
