The ubiquitous commercial use of Lithium-Ion batteries (LIBs) has increased interest in their implementation into efficient energy storage systems for clean and renewable power sources and the electrical transportation industry. Unfortunately, LIBs are not yet technological mature to meet various commercial demands. Consider the following challenges for example,: (1) lower than desired effective ...

An analysis to quantify the effects of packed bed channeling in the narrow passages of the ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Each CO2 adsorbent bed is paired with an upstream desiccant bed to condition the inlet air (i.e. remove water vapor) prior to entry ...

Oil and water are immiscible fluids and they tend to separate very easily when introduced into a flow stream from two different sources in a flow loop. This model studies the development of mixture volume fraction in an oil-water-flow loop with 3 different passive mixing schemes: (i) blind-T, (ii) check valve, and (iii) static mixer. Each device produces different levels of mixture homogeneity ...

This study deals with the 3D modeling of a light photocatalytic textile. This process aims to decontaminate industrial effluents such as water with pesticides. The present study describes the implementation of a reactive transport model in a computational fluid dynamics model developed on a Representative Volume Element (RVE) of the textile, i.e. at the microscopic scale. The final ...

This work proposes the use of inverse problem techniques in connection with COMSOL to estimate the heat flux and the temperature field on a turning cutting tool in transient regime. The main purpose of the present work is to present the improvements performed in relation to the authors’ previous work to develop the complex geometry of a machining process. Specification function, which is an ...

The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction between the stator and the slider. A LiNbO3 piezoelectric substrate is used as a stator where comb structured Al ...

Cholesterol is an essential lipid for human body. The desired total plasma cholesterol for an individual is less than 5.2 mM (200 mg/dL) and it poses a potential health threat when the level is greater than 6.2 mM (240 mg/dL) . Excessive plasma cholesterol causes poor cardiovascular conditions. The experimental fabrication of nano structured biosensor with advanced materials is more expensive ...

Mung bean is a good source of protein, vitamins, certain minerals and antioxidant compounds for the vegetarian population of the country. During storage, high moisture content of mung bean leads to the maximum quality and quantity losses due to the growth of fungus and insects. Thus drying of mung bean grains is an important postharvest operation to increase the shelf life of mung bean. Infrared ...
