Stability of plane Couette and Poiseuille flows rotating about the streamwise axis
Geert Brethouwer
We study the stability of plane Poiseuille flow (PPF) and plane Couette flow (PCF) subject to streamwise system rotation using linear stability analysis and direct numerical simula…
Turbulent heat transfer in open-channel flows with a thermally-conductive porous wall
Seyed Morteza Habibi Khorasani, Geert Brethouwer, Shervin Bagheri
Results of direct numerical simulations (DNS) of porous-wall turbulent flows in open channels with conjugate heat transfer are reported in this work. For the conductive porous wall…
Transitional Atmospheric Boundary Layer in the GABLS4 Experiment Modelled Using the Explicit Algebraic Reynolds-stress Model
Velibor Želi, Stefan Wallin, Arne V. Johansson +1
A recently developed so-called explicit algebraic Reynolds-stress (EARS) model is applied to a transitioning atmospheric boundary layer (ABL). The simulation describes a diurnal cy…
Much faster heat/mass than momentum transport in rotating Couette flows
Geert Brethouwer
Heat and mass transport is generally closely correlated to momentum transport in shear flows. This so-called Reynolds analogy between advective heat or mass transport and momentum…
Passive scalar transport in rotating turbulent channel flow
Geert Brethouwer
Passive scalar transport in turbulent channel flow subject to spanwise system rotation is studied by direct numerical simulations. The Reynolds number is fixed at $2…
Sources and fluxes of scale-energy in the overlap layer of wall turbulence
A. Cimarelli, E. De Angelis, P. Schlatter +3
Direct Numerical Simulations of turbulent channel flows at friction Reynolds number 550, 1000, 1500, are used to analyse the turbulent production, transfer and dissipation mechanis…
Statistics and structure of spanwise rotating turbulent channel flow at moderate Reynolds numbers
Geert Brethouwer
A study of fully developed plane turbulent channel flow subject to spanwise system rotation through direct numerical simulations is presented. In order to study both the influence…
Recurrent bursts via linear processes in turbulent environments
Geert Brethouwer, Philipp Schlatter, Yohann Duguet +2
Large-scale instabilities occurring in the presence of small-scale turbulent fluctuations are frequently observed in geophysical or astrophysical contexts but are difficult to repr…
Hairpins et al. in Turbulent Boundary Layers
Philipp Schlatter, Milos Ilak, Mattias Chevalier +3
A new set of three-dimensional visualisations of a large-scale direct numerical simulations (DNS) of a turbulent boundary layer is presented. The Reynolds number ranges from $Re_θ=…
