Analyzing a turbulent pipe flow via the one-point structure tensors: Vorticity crawlers and streak shadows
Stylianou, F. S.; Pecnik, R.; Kassinos, Stavros C. (2016)Efforts to identify and visualize near-wall structures typically focus on the region y+≳5, where large-scale structures with significant turbulent kinetic energy content reside, such as the high-speed and low-speed streaks ...

The contribution of active and inactive structures to the statistics of a turbulent pipe flow
Stylianou, F. S.; Kassinos, Stavros C. (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
Stylianou, F. S.; Sznitman, J.; Kassinos, Stavros C. (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 ...

The effect of flow rate, head position, and inhaler orientation on the airflow and particle deposition in an mri-based mouth-throat geometry
Stylianou, F. S.; Angeli, S.; Kassinos, Stavros C.; Svensson, M. (International Symposium on Turbulence and Shear Flow Phenomena, TSFP10, 2017)The mouth-throat plays a key role in the administration of inhaled medicines. It is an area of intense filtration, where an unacceptably high fraction of the released drug dose is deposited and thus wasted. Due to the ...

Fully turbulent flow in a physiologically realistic human airway bifurcation
Stylianou, F. S.; Kassinos, Stavros C. (TSFP-9, 2015)Recent computational studies have shown that the airflow in the upper human airways is turbulent during much of the respiratory cycle. A feature of respiratory airflow that poses a challenge to computations based on ...

Article
A general framework for computing the turbulence structure tensors
Stylianou, F. S.; Pecnik, R.; Kassinos, Stavros C. (2015)Good measures of the turbulence structure are important for turbulence modeling, flow diagnostics and analysis. Structure information is complementary to the componentality anisotropy that the Reynolds stress tensor carries, ...
