Deformation of drops by outer eddies in turbulence
Alberto Vela-Martín, Marc Avila
Drop deformation in fluid flows is investigated here as an exchange between the kinetic energy of the fluid and the surface energy of the drop. We show analytically that this energ…
Entropy, irreversibility and cascades in the inertial range of isotropic turbulence
Alberto Vela-Martin, Javier Jimenez
This paper analyses the turbulent energy cascade from the perspective of statistical mechanics, and relates inter-scale energy fluxes to statistical irreversibility and information…
Wall-bounded turbulence control: statistical characterisation of actions/states
Roberto Pastor, Alberto Vela-Martin, Oscar Flores
The present paper reports the results of a Monte Carlo experiment using a turbulent channel flow. Different actions are proposed, varying the size, duration and sign of a localised…
nsCouette -- A high-performance code for direct numerical simulations of turbulent Taylor-Couette flow
Jose Manuel Lopez, Daniel Feldmann, Markus Rampp +3
We present nsCouette, a highly scalable software tool to solve the Navier-Stokes equations for incompressible fluid flow between differentially heated and independently rotating, c…
Time-periodic inertial range dynamics
Lennaert van Veen, Alberto Vela-Martin, Genta Kawahara
We present an unstable periodic orbit in large eddy simulation of an incompressible fluid in a periodic box subject to a constant body force. The width of the inertial range of spa…
A low-storage method consistent with second-order statistics for time-resolved databases of turbulent channel flow up to
Alberto Vela-Martín, Miguel P. Encinar, Adrián García-Gutiérrez +1
In this paper a novel low-storage method for time-resolved databases is presented. This approach reduces the storage cost of time-resolved databases by storing filtered flow fields…
Periodic orbits in Large Eddy Simulation of Box Turbulence
Lennaert van Veen, Alberto Vela Martin, Genta Kawahara +1
We describe and compare two time-periodic flows embedded in Large Eddy Simulation (LES) of turbulence in a three-dimensional, periodic domain subject to constant external forcing.…
The turbulent cascade in five dimensions
José I. Cardesa, Alberto Vela-Martín, Javier Jiménez
To the naked eye, turbulent flows exhibit whirls of many different sizes. To each size, or scale, corresponds a fraction of the total energy resulting from a cascade in five dimens…
