Within wool textile industries, a very important role is played by the so-called finishing processes, in which the textile substrate undergoes steam treatments to achieve the desired level of stabilisation and appearance. Process parameters, namely temperature and moisture content, are known only at the beginning of the process but not in the textile material being treated, where the actual ...

This computational implementation presents a new strategy of coupling two 3D models to satisfy the requirements of the comprehensive model of a unitary Proton Exchange Membrane fuel cell, including its internal geometries and constitutive materials, as well as distinct physical and chemical processes. Those different simultaneous processes required computational effort and the solution was the ...

The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic machines. Nonlinearities due to the high level of acoustic pressure generate DC flows that are superimposed on the ...

Mineral precipitation on to the quartz surface of the lamp jackets in UV disinfection process (fouling) has been recognized as a major problem for UV radiation delivery during disinfection operation. Fouling behavior was observed to be induced thermally and influenced by hydraulic character of the UV disinfection configuration. Fouling process involves momentum, heat, and mass transport within ...

The Constrained Vapor Bubble is a fundamental fluid mechanics experiment that is scheduled to run aboard the International Space Station starting in August 2009. The experiment is focused on looking at evaporation and condensation processes at the contact line, where vapor, liquid and solid meet. Our goal is to understand how processes that occur on the macroscale affect the transport processes ...

The study of multiphase flows inside the microfluidic devices has received much attention recently because of its applications in heat and mass transfer, mixing, microreaction, emulsification and most importantly in MEMS and lab-on-a-chip. We study the influence of an electric field on the interfacial morphologies and their transitions, the phenomenon termed electrohydrodynamics. The literature ...

Scanning electrochemical microscopy (SECM) is a powerful tool recently developed for studying structures and processes in micrometer and submicrometer sized systems. It can probe electron, ion, and molecule transfers, and other reactions at solid-liquid, and liquid-liquid, interfaces . This versatility allows for the investigation of a wide variety of processes, from metal corrosion to ...

Nanorobots may be used in the advancement of medical technology, healthcare, and environment monitoring by swimming in biological fluids flowing in narrow channels of a few hundred nanometers in the area of bio-medical engineering. The pronounced effects in nanometer scale such as increased apparent viscosity and low Reynolds number make the designing of propulsion mechanism a challenging ...

The vertical axis wind turbine design depicted in (Fig.1) is widely considered a wind turbine of a wind power generation system because it can be easily miniaturized, it generates low noise, and it rotates regardless of wind direction. The vertical axis wind turbine has, however, low rotation performance when compared with that of a horizontal axis wind turbine. Therefore, we need to improve the ...

Two-phase electrophoresis is a separation method that combines aqueous two-phase partitioning with electrophoresis and has promise for large scale recovery of biological products. Aqueous two-phase systems formed by adding two polymers, like dextran and polyethylene glycol, to water provide some separation of dissolved species due to differences in solubility of solutes between the phases. ...
