Composite active drag control in turbulent channel flows
Jie Yao, Xi Chen, Fazle Hussain
A composite drag control (CDC) combining the opposition (OC) and spanwise opposed wall-jet forcing (SOJF) methods is studied in a turbulent channel flow via direct numerical simula…
A low-communication-overhead parallel method for the 3D incompressible Navier-Stokes equations
Jiabin Xie, Jianchao He, Yun Bao +1
This paper presents a low-communication-overhead parallel method for solving the 3D incompressible Navier-Stokes equations. A fully-explicit projection method with second-order spa…
Spectral link of the generalized Townsend-Perry constants in turbulent boundary layers
Björn Birnir, Luiza Angheluta, John Kaminsky +1
We propose a minimal spectral theory for boundary layer turbulence that captures very well the profile of the mean square velocity fluctuations in the stream-wise direction, and gi…
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…
Aerodynamic Heating in Hypersonic Boundary Layers:\ Role of Dilatational Waves
Yiding Zhu, Xi Chen, Jiezhi Wu +3
The evolution of multi-mode instabilities in a hypersonic boundary layer and their effects on aerodynamic heating are investigated. Experiments are conducted in a Mach 6 wind tunne…
Analytic prediction for planar turbulent boundary layers
Xi Chen, Zhen-Su She
Analytic predictions of mean velocity profile (MVP) and streamwise () development of related integral quantities are presented for flows in channel and turbulent boundary layer…
