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…
Renormalization constants of local operators for Wilson type improved fermions
C. Alexandrou, M. Constantinou, T. Korzec +2
Perturbative and non-perturbative results are presented on the renormalization constants of the quark field and the vector, axial-vector, pseudoscalar, scalar and tensor currents.…
Renormalization constants for one-derivative fermion operators in twisted mass QCD
C. Alexandrou, M. Constantinou, T. Korzec +2
We present perturbative and non-perturbative results on the renormalization constants of the local and one-derivative vector and axial vector operators. Non-perturbative results ar…
Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions
Martha Constantinou, Petros Dimopoulos, Roberto Frezzotti +4
In this work we calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculat…
BK-parameter from Nf = 2 twisted mass lattice QCD
ETM Collaboration, M. Constantinou, P. Dimopoulos +12
We present an unquenched lattice computation of the parameter which controls oscillations. A partially quenched setup is employed with two maximally…
