Analysis of airflow through experimental rural buildings: Sensitivity to turbulence models
(2007)Fullscale experimental data and computational fluid dynamics (CFD) methods are used to determine the accuracy of four different turbulence models [standard kε, kε renormalisation group (RNG), kε realisable, Reynolds ... 
Concise and accurate solutions to halfspace binarygas flow problems defined by the McCormack model and speculardiffuse wall conditions
(2004)An analytical version of the discreteordinates method (the ADO method) is used to establish concise and particularly accurate solutions to the viscousslip and the halfspace thermalcreep problems for a binary gas mixture. ... 
Deformation vs. flow and waveletbased models of gradient plasticity: Examples of axial symmetry
(2006)The modest goal of this article  the first in a series of three dedicated to Kirk Valanis  is to discuss and compare (in terms of their constitutive and variational formulation, boundary conditions and sizedependent ... 
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 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 ... 
The McCormack model: Channel flow of a binary gas mixture driven by temperature, pressure and density gradients
(2004)An analytical version of the discreteordinates method (the ADO method) is used to establish concise and particularly accurate solutions to the problems of Poiseuille flow, thermalcreep flow and diffusion flow for a binary ... 
On the effect of the boundary conditions and the collision model on rarefied gas flows
(2011)In this work, the effect of the gassurface interaction law and of the intermolecular collision model is examined by solving, using the DSMC method, the heat transfer problem between parallel plates and the nonisothermal ... 
Packetostatics: Deployment of massively dense sensor networks as an electrostatics problem
(2005)We investigate the spatial distribution of wireless nodes that can transport a given volume of traffic in a sensor network, while requiring the minimum number of wireless nodes. The traffic is created at a spatially ... 
Pipe response under concentrated lateral loads and external pressure
(2006)The paper focuses on the denting the response of pipeline segments subjected to lateral quasistatic wedge loading, in the presence of internal pressure. Nonlinear finite element models of pipeline segments, which are in ... 
Results on the viscous slip coefficient for binary gas mixtures
(2008)The viscous slip coefficients for the binary gas mixtures of NeAr, HeAr and HeXe are estimated by solving the McCormack kinetic model equation subject to Maxwell diffusespecular scattering boundary conditions. The ... 
Shear driven microflows of gaseous mixtures
(2004)A mesoscale kinetictype approach is proposed to solve shear driven micro flows of binary gas mixtures in MEMS. The coupled linear integraldifferential equations, which formally describe the flow, are solved using the ... 
Sloshing effects on the seismic design of horizontalcylindrical and spherical vessels
(2004)The paper concerns earthquakeinduced sloshing analysis in horizontalcylindrical and spherical industrial vessels. More specifically, the paper focuses on the calculation of the total force in such vessels, due to horizontal ... 
Threedimensional convective cooling in a vertical channel with flushmounted heat sources
(2003)Threedimensional free convection in a vertical channel with spatially periodic, flushmounted heat sources is investigated by a spectral element method. All numerical solutions are obtained using a timeaccurate ... 
The use of strain gradient elasticity in modelling tissues: The case of the human heart
(2010)In recent years, strain gradient elasticity has been used to capture size effects in stiffness and toughness that appear in structures of different sizes. An important aspect of such theories, often taken of little notice, ...
