The high temperature measurement of thermal conductivity is vital for predicting nuclear fuel performance both during reactor operation and accident conditions. The proposed method uses experimental thermograms obtained via high temperature laser-flash heating of a disc-shaped sample ... Read More

Constraints on Ocean Floor Permeability from Hydrothermal Modelling new

S. Titarenko[1], A. McCaig[1]
[1]School of Earth and Environment, University of Leeds, Leeds, UK

The Atlantis massif is a domal submarine seamount close to the mid-Atlantic Ridge at 30 °N. Close to the crest of the Massif, the Lost City hydrothermal field (LCHF) has been active for at least 120,000 years, venting fluids with a temperature of 40-90 °C. 5 km north of Lost City, a ... Read More

Modelling of a Wool Hydrolysis Reactor new

M. Giansetti[1], A. Pezzin[1], S. Sicardi[1], G. Rovero[1]
[1]Politecnico di Torino, Torino, Italy

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes ... Read More

Analysis to Determine Optimum Strain Gauge Locations for SENSEWHEEL new

T. Suzuki[1], C. Holloway[1], S. Taylor[1]
[1]University College London, London, UK

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx ... Read More

Capacitive Deionization for Desalinating Complex Streams new

D. Cardoen[1,2], B. B. Sales[1], J. Helsen[1], A. Verliefde[2]
[1]VITO, Mol, Belgium
[2]Ghent University, Ghent, Belgium

Capacitive deionization (CDI) is a desalination technology which is based on the storage of ions in the electrical double layer of a pair of oppositely polarized porous carbon electrodes, which are usually assembled using activated carbon particles (Figure 1). It is efficiently deployed ... Read More

Pump and Ejector Design in Wastewater Treatment Pilot Equipment new

G. Actis Grande[1], A. Pezzin[1], G. Rovero[1]
[1]Politecnico di Torino, Torino, Italy

Ozone treatment is an oxidative process used in wastewater treatment plant to demolish complex organic molecule. In the case of textile industry is required to adequately remove residual color, demolishing the chromophoric bonds or groups in the dye molecules. A useful method for ... Read More

Particle Beam Tracking with COMSOL Multiphysics® Software new

O. Karamyshev[1], L. J. Devlin[1], C. P. Welsch[1]
[1]University of Liverpool, Liverpool, UK

Accurate and efficient tracking is important for designing particle accelerators as well as many other applications which use electromagnetic fields to control particles. We have developed a tracking code in MATLAB® Simulink® which uses electric and magnetic fields calculated in COMSOL ... Read More

Numerical Modelling of the Plasma Discharge During Electron Beam Welding (EBW) new
