Electrowetting on Dielectric (EWOD) is a versatile tool for performing basic operations in Digital Microfluidic Systems. In EWOD, surface tension between a liquid droplet and solid substrate is modulated by applying voltage to an electrode and a hydrophobic surface is transformed into a ... En savoir plus
Oxygen delignification is a technology established worldwide and a common operation in pulp mills that use Kraft cooking. The reasons for using this technology are the reduction of organochlorine compounds in the effluents, and economy of chemicals in the bleaching stage. The objective ... En savoir plus
Patch antennas are widely used in communications links with unmanned aerial vehicles. Their hemispherical send and receive patterns enable the systems to maintain radio frequency contact over a wide range of vehicular attitudes. A microstrip-fed design offers other attractive features ... En savoir plus
The Lévêque problem is an idealized simple situation concerning the influence of the boundary on the distribution of temperature or mass in Hagen-Poiseuille flow. Here, the performance of numerical solutions is examined for a range of Péclet numbers, spanning 11 orders of magnitude. We ... En savoir plus
Scramjet inlet design remains as a key aspect for hypersonic flight. To assess the inlet design, the performance parameters namely; air-capture ratio, total pressure efficiency, inlet drag coefficient, and kinetic energy efficiency are evaluated and analysed. In the current study ... En savoir plus
This work focuses on the numerical analysis conducted on the prototype sensor for the measurement of highly concentrated radiative heat fluxes, based on an inverse heat transfer method, realized at the ENEA Portici Research Center in collaboration with the DETEC department of the ... En savoir plus
Carbon Steel pipes are used as feeder pipes in Pressurized Heavy Water Nuclear Reactors for carrying the coolant from the inlet headers to the coolant channel and again from outlet of the coolant channel to the outlet headers and are part of the Primary Heat Transport (PHT) System of ...

The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir ... En savoir plus
Phosphoric acid doped polybenzimidazole (PBI) membranes are commonly used in today’s high-temperature polymer-electrolyte-membrane (HTPEM) fuel cell technology. COMSOL Multiphysics is used to model and simulate the three-dimensional, single-phase, non-isothermal overall cell behaviour ... En savoir plus
