3-D simulations of flows in the reconstituted lake Karla, Thessaly, Greece
(2010)We report on three-dimensional flow simulations carried out in order to describe the dominant water current patterns in the reconstituted lake Karla. The flow is considered to be generated mainly by wind shear while the ... -
Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
Dynamic simulations of an encapsulated microbubble translating in a tube at low capillary and Reynolds numbers
(2021)The dynamic translation of a micron-sized encapsulated bubble is investigated numerically inside a horizontal tube where liquid flows under constant pressure drop, when the effect of gravity is neglected. The coating of ... -
Effect of soil characteristics on shear strength of sands
(2018)The paper presents the results of a laboratory investigation into the influence of (a) mineral composition and angularity of sand grains and (b) fines type and content on the strength parameters of sandy soils tested at ... -
EXPERIMENTAL RESEARCH ON IMPROVEMENT OF THE DUCTILITY OF R/C SEISMIC WALLS THROUGH SLIP PREVENTION WITH THE USE OF STEEL RHS
(2022)Several researchers propose placing diagonal reinforcing bars at the base of the wall to treat the shear slip, while others have suggested various ways to address this problem associated with halting the effects incurred ... -
Finite element analysis of buried steel pipelines under strike-slip fault displacements
(2011)The present paper investigates the mechanical behavior of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and crosses the pipeline axis at a certain angle. The interacting ... -
Friction factor in nanochannel flows
(2016)Non-equilibrium molecular dynamics simulations are employed in order to access the detailed atomic behavior of fluids moving in nanochannels and to quantify the associated energy dissipation. Nanochannels of various degrees ... -
Hemodynamic profile of two aortic endografts accounting for their postimplantation position
(2017)Endovascular aneurysm repair (EVAR) is a clinically effective technique for treating anatomically eligible abdominal aortic aneurysms (AAAs), involving the deployment of an endograft (EG) that is designed to prevent blood ... -
Hierarchical Bayesian Uncertainty Quantification for a Model of the Red Blood Cell
(2021)Simulations of blood flows in microfluidic devices and physiological systems are gaining importance in complementing experimental and clinical studies. The predictive capabilities of these simulations hinge on the parameters ... -
Influence of permeable bed and channel width on turbulent characteristics in inclined open channel flows
(2017)For the investigation of the influence of the kind of the different permeable bed and channel width in inclined open channels, a series of laboratory experiments were performed. Experiments were conducted in two channels ... -
Lattice kinetic schemes in fusion plasmas
(2008)Lattice Boltzmann Methods (LBM) are an established alternative approach for numerical simulations of a large spectrum of physical processes. They are based on a mesoscopic analysis of the underlying physics through a ... -
Linear harmonic oscillatory rarefied gas flow with arbitrary frequency in comb finger blocks
(2021)The linear oscillatory two-dimensional rarefied gas flow in the zig-zag channel between the shuttle and stator fingers of typical comb elements, due to the harmonic motion of the shuttle finger with arbitrary frequency, ... -
Mechanical behavior of buried steel pipelines crossing strike-slip seismic faults
(2011)The present paper investigates the mechanical behaviour of buried steel pipelines, crossing active strike-slip tectonic faults. The fault plane is vertical and perpendicular to the pipeline axis. The interacting soil-pipeline ... -
Mechanical performance of laser spot-welded joints in Al-Al/Cu solar thermal absorbers
(2018)The mechanical performance of laser spot welded joints used in Al-Cu and Al-Al thermal absorber systems has been evaluated under different laser welding and mechanical loading conditions. In the experimental investigation, ... -
