In wall-bounded turbulent flow calculations, the past focus has been directed to modelling of Reynolds-stress gradients. Not much attention paid effects numerical methods used calculate these terms and modelled equations. Discrepancies between model calculations measurements are quite often attributed incorrect modelling, while suitability accuracy seldom scrutinized. Instead, alternate near-wa...

We review some of our recent efforts in developing upscaling methods for simulating the flow transport through heterogeneous porous media. In particular, the steady flow transport through highly heterogeneous porous media driven by extraction wells and the flow transport through unsaturated porous media will be considered. Mathematics subject classification: 65F10, 65F30.

in the present work, an engineering method is developed to predict laminar and turbulent heating-rate solutions for blunt reentry spacecraft at hypersonic conditions. the calculation of aerodynamic heating around blunt bodies requires alternative solution of inviscid flow field around the hypersonic bodies. in this paper, the procedure is of an inverse nature, that is, a shock wave is assumed a...

a numerical study of 3d electrokinetic flows through micromixers was performed. the micromixers considered here consisted of heterogeneous rectangular microchannels with prescribed patterns of zeta-potential at their walls. numerical simulation of electroosmotic flows within heterogeneous channels requires solution of the navier-stokes, ernest-plank and species concentration equations. it is kn...

In the last decade the ARTigo platform collected descriptive tags for historic artworks through the help of different games with a purpose (GWAP). Using the additional provided creation date of the artworks, the goal of this thesis is to detect events relevant in an art historic context. To achieve this goal the relative amount of distinct tags is analyzed over time. Locating the events is acco...

Recently, Gigabit-Ethernet is rapidly deployed, for the requirement of providing high-speed access technology on service provider, easy and simple management with legacy Ethernet, and to be line-up from Ethernet to 10G Ethernet with standardization of IEEE. Furthermore, very high scaled MAN(MetroPolitian Network) has constructed on several country by Gigabit Ethernet and also made main streams ...

delay is one of the principal measures of performance used to determine the level of service (los) at signalized intersections and several methods have been widely used to estimate vehicular delay. very few studies only have been carried out to estimate delay at signalized intersections under mixed traffic conditions prevailing in developing countries like india. in the present study, various p...
