A 2D cellular automaton biofilm detachment algorithm
(2012)A cellular-automaton based two-dimensional biofilm detachment module is developed. The module is an improvement of previously presented methodologies for modeling biofilm detachment under the influence of hydrodynamic ... -
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. ... -
Concise and accurate solutions to half-space binary-gas flow problems defined by the McCormack model and specular-diffuse wall conditions
(2004)An analytical version of the discrete-ordinates method (the ADO method) is used to establish concise and particularly accurate solutions to the viscous-slip and the half-space thermal-creep problems for a binary gas mixture. ... -
Estimation of the Poiseuille number in gas flows through rectangular nano- and micro-channels in the whole range of the Knudsen number
(2009)Based on a recent work (Valougeorgis, Phys. Fluis 19(9):091701.1-091701.4, 2007), the Poiseuille number for gas flows through channels of orthogonal cross sections is estimated in the whole range of the Knudsen number from ... -
Finite element modeling of porous solid propellants
(2005)The effect of porosity on the constitutive response of a linearly viscoelastic solid that obeys a constitutive law of the standard differential form is investigated under small strain deformation conditions. It is demonstrated ... -
Gas flow in a grooved channel due to pressure and temperature gradients
(2006)The flow of a gas in a grooved nano or micro channel, due to the imposed pressure and temperature gradients in the longitudinal direction, is investigated via a kinetic approach. The solution is valid in the whole range ... -
Haemodynamic performance of AFX and Nellix endografts: A computational fluid dynamics study
(2018)OBJECTIVES The objective of this study is to analyse the flow conditions in the AFX and Nellix endografts (EGs) accounting for their postimplantation configuration in patients with an endovascular aneurysm repair-treated ... -
Hydrodynamic loading and wave run-up on "elliptical" breakwaters
(2016)This paper applies a semi-analytical solution methodology for the linear hydrodynamic diffraction induced by plane breakwaters assimilated as degenerate elliptical cylinders subjected to incident waves. The solution of the ... -
Hydrodynamics and near trapping effects in arrays of multiple elliptical cylinders in waves
(2018)The purpose of the present study is the investigation of the hydrodynamic interactions induced by arrays of elliptical cylinders subjected to regular waves. The solution methodology employs linear potential theory and is ... -
Numerical Investigation of Wind Driven Circulation and Horizontal Dispersion in the Surface Layer of a Re-flooded Shallow Lake
(2016)The re-flooded lakes with unique natural and cultural values that are under threat from anthropogenic pressure, consist a very important section of fresh water resources management in the Mediterranean. Lake Karla, positioned ... -
Numerical study of particle transport in a river with a lateral harbor basin
(2017)In this study, the development and application of two mathematical models used to investigate particle transport in a river with a lateral harbor basin are presented: a two-dimensional depth-averaged hydrodynamic model and ... -
On the seismic behaviour and design of liquid storage tanks
(2011)The paper examines some special issues on the structural behaviour of upright-cylindrical liquid storage tanks, which are widely used in industrial facilities and for water storage. Two main design standards are considered: ... -
Optimum design of the entrance of a fishpond laterally to the main stream of an open channel
(2017)In this study, the optimum design of the entrance of a fishpond laterally to the main flow of an open channel was investigated numerically and experimentally. The flow characteristic measurements were realized with the PIV ... -
Sloshing effects on the seismic design of horizontal-cylindrical and spherical vessels
(2004)The paper concerns earthquake-induced sloshing analysis in horizontal-cylindrical and spherical industrial vessels. More specifically, the paper focuses on the calculation of the total force in such vessels, due to horizontal ... -
SPH BASED STUDY OF CONFINED MICROFLOWS CHARACTERIZED BY ABRUPT CHANGES IN CROSS-SECTIONAL AREA
(2021)In this paper, we investigate the application of Smoothed Particle Hydrodynamics (SPH) method to the computation of flows in microchannels with sudden expansion. Numerical modeling with SPH involves the treatment of flowing ... -
Surface anisotropy for monitoring the wear of IC engine cylinders
(2004)The present work proposes a methodology for monitoring the wear of internal combustion engine cylinders. This could be useful in calculating the time at which maintenance should be done on such a tribosystem or in determining ...
