In some last decades, increasing air pollution and its consequences captivate attention of researchers from all over the world. Scientists have developed some alternate fuels to eliminate the exhaust pollutants. In this paper, idea of using compressed air as a power source in natural gas engines is presented and discussed to explore the concept of new energy vehicles. However, energy densityof ...

novement of the end of the bar (e) and assures a quick and positive movement of the valve when the vessel (d) moves from the "down" to the "up" position. A suitable counter weight is suspended from the bar (e). As indicated in the diagram, when the vessel (d) is in the "up" position air pressure from the compressed air main forces the culture solution up into the sand containers. As the solutio...

Globally faster consumption of hydrocarbon fuel in the transport sector is posing threat to environmental and ecological imbalances and thereby depletion of hydro-carbon fuel is causing another challenge to oil reserves. In view of these issues extensive researches are being carried out to explore the alternative energy source and or to find out appropriate energy conversion system. The atmosph...

of the Dissertation Fault Detection and Diagnosis for A Multi-Actuator Pneumatic System by Kunbo Zhang Doctor of Philosophy in Mechanical Engineering Stony Brook University 2011 In pneumatic actuating systems, various kinds of faults are key factors in degrading system performance and increasing air consumption. It is therefore valuable to monitor pneumatic systems and implement predictive main...

This paper deals with new concept of compressed air energy storage system using atmospheric air at ambient temperature as a zero pollution power source for running motorbikes. The proposed motorbike is equipped with an air turbine in place of an internal combustion engine, and transforms the energy of the compressed air into shaft work. The mathematical modeling and performance evaluation of su...

Induction motors (IMs) are commonly used in various industrial applications. To improve energy consumption efficiency, a reliable IM health condition monitoring system is very useful to detect IM fault at its earliest stage to prevent operation degradation, and malfunction of IMs. An intelligent harmonic synthesis technique is proposed in this work to conduct incipient air-gap eccentricity faul...

BACKGROUND To the best of our knowledge, only 14 cases of orbital or periorbital compressed air injuries from air guns or hoses have been reported in the literature. CASE PRESENTATION A 30-year-old man was accidentally injured when a compressed air hose nozzle hit his right eye. The right half of his face was markedly swollen and a skin laceration near the right medial canthus was identified....

A thermochemical conversion (TCC) process was developed to convert swine manure into an oil product in a high temperature and pressure environment. The objective of this study was to examine the effects of different process gases, including CO, H2, CO2, N2, and compressed air, on the efficiencies of oil production and waste reduction, and to explore the possibility of replacing costly reducing ...

In order to study life support key techniques in mine refuge station, test the clinical emergency response of participants and human survival parameters in rescue state. A manned test with 50 miners for 48h in a real underground refuge station was conducted in Guilaizhuang gold mine. The experiment simulated rescue living environment of human and consisted of three stages (the passive stage, th...
