Carbon nanoparticles are very useful in solar thermal applications as they absorb much of the solar spectrum and can be inexpensive. Water-based carbon nanofluids with two different concentrations (3 and 33 mg·l-1) were prepared with sodium dodecyl sulphate as surfactant to achieve good high-temperature stability with a constant mean particle size...
The potential use of molten salt-based nanofluids as thermal energy storage material in Concentrated Solar Power plants has gained attention over the last years due to their enhanced storage capacity. The possible effects of the salt-based nanofluid production at industrial scale have not been yet investigated, as this could influence the nanoparti...
In this work a detailed experimental hydrodynamic characterization of a needle sparger rectangular bubble column has been performed. The liquid velocity profiles and bubble plume oscillation frequency have been measured by means of laser Doppler anemometry (LDA), and the bubble velocity map by particle image velocimetry (PIV). In this way, the infl...
A pleural drainage system must be capable of efficiently evacuating the air or fluids from the pleural cavity so that adequate lung reexpansion can take place. The air flow and negative pressure of the system will depend on the particular design of each model. This experimental study analyzes the specifications and performance of the pleural draina...
En el presente trabajo se desarrolló una metodología para la estimación de consumos de una red de distribución de agua potable, cuando no se cuenta con equipos de medición instalados en la red para la cuantificación de los mismos. Para tal fin se analizó la red de distribución de agua potable de la ciudad de Barquisimeto, que abastece a una poblaci...
The concept of Total Quality has been incorporated into technology production and design philosophy all over the world. It is aimed at satifying customers as the end users of the product or service in question. Quality is therefore an overall concept including everything concerned with the objective of achieving excellence, which should be the goal...
La fiabilidad del sistema hidráulico es un tema de capital importancia en la situación actual donde la sociedad cada vez es más exigente, la tecnología debe adaptarse a las necesidades y el ahorro adquiere mayor interés. En la línea de mejorar la calidad de todo cuanto nos rodea, este artículo pretende introducir al lector en los conceptos de fiabi...
The pressure-reducing-valve(PRV) optimization proposed in the paper does not yield global optimum, as diameter optimization and PRV optimization are considered separately.Before adopting such a technique with quick response ands low-acting PRVs, the following points are to be considered from operational and technoeconomic considerations
The growing concern on improving the use of water in distribution systems, requires increasing the quality and the reliability in such systems. This paper presents a series of techniques aimed at reducing water losses and increasing the efficiency in the supply.
The proposed methodology covers the selection and optimization criterion of the strateg...
This book contains the lectures given in the International Course "Improving efficiency and reliability in water supply systems", hosted and sponsored by the Menendez Pelayo International University (U.I.M.P.) and co-sponsored by Aguas de Valencia, the British Council and the EC Cornett and Erasmus programmes. The short course took place in Valenci...
La justificada y creciente preocupación por mejorar el aprovechamiento del agua en los sistemas de abastecimiento exige aumentar la calidad y rendimiento de dichos sistemas. El presente artículo presenta una serie de técnicas encaminadas a reducir las pérdidas de agua e incrementar la eficiencia de los abastecimientos. La metodología propuesta prop...
Economical design of hydraulic networks has been a subject of research for some time. Piping has been the main focus of this research because it represents the greatest percentage of the investment in a network. Pipe cost increases with size, but in addition, depends on the material chosen and the pipe class (thickness). However, optimization metho...
When a problem of hydraulic transients with entrapped air in pipelines and/or with water-column separation is tackled, the variation of the length of the liquid column is not usually taken into account. In this paper (due largely to the assumption of a system with a cross section at the air-water interface in a horizontal pipeline), it is shown tha...
The cost effective design of hydraulic networks has been traditionally studied from the point of view of the relationship between hydraulic variables and economic parameters, with piping being the main element studied. The reason is clear: the piping is by far the most costly item of a projected network. However it is not usual to find an explicit...
Durante las dos últimas décadas el Parque Nacional de las Tablas de Daimiel ha sufrido graves impactos causados por la disminución de las aportaciones de recursos hídricos del acuífero 04.04 "Mancha Occidentar'. En este trabajo se presentan las conclusiones obtenidas acerca de la relación entre la evolución temporal de la superficie en regadío y la...
