The Behaviour of a Turbulent Buoyant Jet into Flowing Environment

Keramaris E., Pechlivanidis G. (2016)

In this study the mean axial velocity at the centreline of a buoyant jet which is discharged vertically upwards from a source, into flowing environment inside a denser ambient fluid (water), in an open channel, is investigated. ...

Computational Study of the Optimum Gradient Magnetic Field for the Navigation of the Spherical Particles in the Process of Cleaning the Water from Heavy Metals

Karvelas E.G., Lampropoulos N.K., Karakasidis T.E., Sarris I.E. (2016)

The usage of magnetic spherical nanoparticles, coated with substances and driven to targeted areas in tanks, is proposed for cleaning the water from heavy metals. In the present paper, a computational study for the estimation ...

Determining a Socially Fair Drinking Water Pricing Policy: The Case of Kozani, Greece

Kanakoudis V., Tsitsifli S., Gonelas K., Papadopoulou A., Kouziakis C., Lappos S. (2016)

The Water Framework Directive (WFD) 2000/60/EC clearly indicates that all member states should develop and apply water pricing policies to recover the Full Water Cost (FWC) (including the direct cost, the environmental and ...

Developing an Optimization Algorithm to form District Metered Areas in a Water Distribution System

Korkana P., Kanakoudis V., Makrysopoulos A., Patelis M., Gonelas K. (2016)

Exploiting the numerous possibilities that unfold from the inter-connection of Matlab and Epanet software, an algorithm is produced in C++ language. The algorithm reads all the significant data of the water distribution ...

Estimating the Water Resources Vulnerability Index in the Adriatic Sea Region

Kanakoudis V., Tsitsifli S., Papadopoulou A., Curk B.C., Karleusa B. (2016)

The Adriatic Sea countries face significant problems regarding cross-border water resources management. DRINKADRIA project aims at developing a common methodological framework, for efficient and effective cross border water ...

Experimental and Numerical Study of Turbulent Flow in Open Channels with Impermeable and Porous Bed

Keramaris E., Pechlivanidis G., Kasiteropoulou D., Michalolias N., Liakopoulos A. (2016)

In order to experimentally and numerically investigate turbulent flow in an open channel with porous (vegetated) and impermeable bed 2D Particle Image Velocimetry (PIV) and a Computational Fluid Dynamical (CFD) model were ...

Experimental Determination of Hydraulic Conductivity at Unsaturated Soil Column

Sakellariou-Makrantonaki M., Angelaki A., Evangelides C., Bota V., Tsianou E., Floros N. (2016)

Hydraulic Conductivity (K) is an important hydraulic parameter as it affects the environment by controlling infiltration, irrigation rate, and consequently the water movement through the ground. In order to determine ...

Forming District Metered Areas in a Water Distribution Network Using Genetic Algorithms

Korkana P., Kanakoudis V., Patelis M., Gonelas K. (2016)

Dividing a water distribution network into District Metered Areas (DMAs) is the first vital step towards water loss management. It is a multivariate problem. Techniques based on Genetic Algorithms is a proven way to provide ...

Inactivation, removal, and regrowth potential of opportunistic pathogens and antimicrobial resistance genes in recycled water systems

Drigo B., Brunetti G., Aleer S.C., Bell J.M., Short M.D., Vasileiadis S., Turnidge J., Monis P., Cunliffe D., Donner E. (2021)

With two thirds of the global population living in areas affected by water scarcity, wastewater reuse is actively being implemented or explored by many nations. There is a need to better understand the efficacy of recycled ...
