Application of the ASBM-SA closure in a turbulent flow over a hump in the presence of separation control
Constantinos F. Panagiotou, Fotos S. Stylianou, Elias Gravanis +2
We demonstrate the coupling between the Algebraic Structure-Based Model (ASBM) and the one-equation Spalart-Allmaras (SA) model, which provides an easy route to bringing structure…
An explicit algebraic closure for passive scalar-flux: Applications in heated channel flows subjected to system rotation
Constantinos F. Panagiotou, Fotos S. Stylianou, Elias Gravanis +2
We present an algebraic model for turbulent scalar-flux vector that stems from tensor representation theory. The resulting closure contains direct dependence on mean velocity gradi…
Isotropic turbulence in compact space
Elias Gravanis, Evangelos Akylas
Isotropic turbulence is typically studied numerically through the direct numerical simulations (DNS). The DNS flows are described by the Navier-Stokes equation in a 'box', defined…
Generalized Batchelor functions of isotropic turbulence
Elias Gravanis, Evangelos Akylas
We generalize Batchelor's parameterization of the autocorrelation functions of isotropic turbulence in a form involving a product expansion with multiple small scales. The richer s…
On the stationarity of linearly forced turbulence in finite domains
E. Gravanis, E. Akylas
A simple scheme of forcing turbulence away from decay was introduced by Lundgren some time ago, the `linear forcing', which amounts to a force term linear in the velocity field wit…
Shock waves and Birkhoff's theorem in Lovelock gravity
Elias Gravanis
Spherically symmetric shock waves are shown to exist in Lovelock gravity. They amount to a change of branch of the spherically symmetric solutions across a null hypersurface. The i…
