DSMC simulation of pressure driven binary rarefied gas flows through short microtubes
(2011)Binary gas flows driven by pressure gradient through short microtubes are studied by using an upgraded version of the Direct Simulation Monte Carlo (DSMC) method. Two types of mixtures, He/Xe and Ne/Ar, are examined. Several ... -
Evaluation of pavement maintenance and strengthening techniques
(2019)Prospects of the 21st Century assert that road networks will continue to expand while the existing road infrastructure will remain a valuable asset to be smartly and effectively preserved, operated and managed. The challenge ... -
Gas flow and heat transfer simulation in MEMS via a mesoscopic approach
(2004)The flow problem of binary gaseous mixtures in rectangular micro channels due to small pressure, temperature and molar concentration gradients over the whole range of the Kn number is solved. The solution is based on a ... -
Gas mixing and final mixture composition control in simple geometry micro-mixers via DSMC analysis
(2019)The mixing process of two pressure driven steady-state rarefied gas streams flowing between two parallel plates was investigated via DSMC (Direct Simulation Monte Carlo) for different combinations of gases. The distance ... -
The influence of fines on the deformation properties of sands imposed to dynamic loading
(2015)This paper presents the results of a laboratory investigation into the influence of fines content on the deformation properties of sandy soils. In particular, specimens of artificial mixtures of sand with nonplastic and ... -
Influence of Zeolite and Posidonia oceanica (L.) in the Reduction of Heavy Metal Uptake by Tobacco (Nicotiana tabacum) Plants of Central Greece
(2017)In two soils from Central Greece, a pot experiment was conducted with the addition of mixture at various ratios of zeolite and compost (based on Posidonia oceanica (L.) leaves) applied at a rate of 5% w/w (calculated on a ... -
Investigation of the reaction of ethanol-steam mixtures in a YSZ electrochemical reactor operated in a fuel cell mode
(2006)In the present investigation ethanol-water mixtures were directly fed to a yttria stabilized zirconia (YSZ) electrochemical reactor operated in a fuel cell mode and the preliminary results are presented and discussed. ... -
Performance of free-space optical communications over a mixture composite irradiance channel
(2017)The performance of a typical free-space optical link using a recently proposed composite model for turbulence and pointing error effects is studied. This model offers analytical tractability in the statistical description ... -
Rarefied gas mixture flow between plates of arbitrary length due to small pressure difference
(2012)The linearized flow of a binary gas mixture between two parallel plates of any length driven by a small pressure difference is numerically solved based on the McCormack kinetic model. In this case the flow is not fully ... -
Resonant column testing on Portland cement concrete containing recycled asphalt pavement (RAP) aggregates
(2018)This study deals with material properties of Portland cement concrete (PCC) made with aggregate that is replaced with recycled asphalt pavement (RAP). A series of PCC mixtures were produced and tested in uniaxial compression ... -
Results on the viscous slip coefficient for binary gas mixtures
(2008)The viscous slip coefficients for the binary gas mixtures of Ne-Ar, He-Ar and He-Xe are estimated by solving the McCormack kinetic model equation subject to Maxwell diffuse-specular scattering boundary conditions. The ... -
Tomographic Image Reconstruction with a Spatially Varying Gamma Mixture Prior
(2018)A spatially varying Gamma mixture model prior is employed for tomographic image reconstruction, ensuring effective noise elimination and the preservation of region boundaries. We define a line process, modeling edges between ... -
A Tractable Model for Turbulence- and Misalignment-Induced Fading in Optical Wireless Systems
(2016)Composite models for the combined effect of both scintillation- and misalignment-induced fading in terrestrial optical wireless systems are often expressed in terms of higher order special functions, making, thus, the ...
