[EN] We present a new set of direct numerical simulation data of a turbulent plane Couette flow with constant wall-normal transpiration velocity V-0, i.e. permeable boundary conditions, such that there is blowing on the ...

[EN] The length and width of the long and wide structures appearing in turbulent Couette flows are studied by means of a new dataset of direct numerical simulation covering a stepped transition from pure Couette flow to ...
[EN] The calculation of turbulence statistics is considered the key unsolved problem of fluid mechanics, i.e., precisely the computation of arbitrary statistical velocity moments from first principles alone. Using symmetry ...
[EN] A new direct numerical simulation of a Poiseuille channel flow has been conducted for a friction Reynolds number of 10000, using the pseudospectral code LISO. The mean streamwise velocity presents a long logarithmic ...
