Grid-point and time-step requirements for direct numerical simulation and large-eddy simulation
Xiang I. A. Yang, Kevin Patrick Griffin
We revisit the grid-point requirement estimates in Choi and Moin [Phys. Fluid, 24, 011702 (2012)] and establish more general grid-point requirements for direct numerical simulation…
3D flow motions in the viscous sublayer
Santosh Kumar Sankar, Xinyi Huang, Xiang Yang +1
We employ novel digital Fresnel reflection holography to capture the 3D flows within the viscous sublayer of a smooth-wall turbulent channel flow at Reτ=400. The measurements revea…
On skin friction in wall-bounded turbulence
Zhenhua Xia, Peng Zhang, Xiang I. A. Yang
In this paper, we derive mathematical formulas for the skin friction coefficient in wall-bounded turbulence based on the Reynolds averaged streamwise momentum equation and the tota…
Bifurcation and multiple states in plane Couette flow with spanwise rotation
Xiang Yang, Zhenhua Xia
We present a derivation that begins with the Navier--Stokes equation and ends with a prediction of multiple statistically stable states identical to those observed in a spanwise ro…
