Structure-based turbulence model: Application to a rotating pipe flow
(2002)
A new approach for modeling the one-point turbulence statistics, which takes into account the information on turbulence structure, has been suggested in Kassinos and Reynolds (Report TF-61, Thermosciences Division, Department ...
Structure and scales in turbulence modeling
(2002)
The enstrophy of the large-scale energy-containing turbulence is proposed as the second turbulence scale for use, in conjunction with the turbulence energy, in two-scale one-point engineering turbulence models. Its transport ...
Large-eddy simulations of the turbulent Hartmann flow close to the transitional regime
(2007)
A series of large-eddy simulations (LES) of turbulent and transitional channel flows of a conductive fluid under the effect of a uniform magnetic field applied in the wall-normal direction, usually referred to as Hartmann ...
The contribution of active and inactive structures to the statistics of a turbulent pipe flow
(2017)
The current study is a short follow-up to our most recent work (Stylianou et al., 2016), where among other things we have presented an effective criterion suitable for distinguishing large-scale coherent structures with ...
Direct numerical simulation of particle laden flow in a human airway bifurcation model
(2016)
During the delivery of inhaled medicines, and depending on the size distribution of the particles in the formulation, airway bifurcations are areas of preferential deposition. Previous studies of laminar flow through airway ...
An analytical solution for rapidly distorted turbulent shear flow in a rotating frame
(2006)
In this study we apply rapid distortion theory to the case of nonstratified homogeneous turbulence that is sheared in a frame that counter-rotates at a rate that matches in magnitude the rotation associated with the mean ...
