Book Synopsis Optimización del tiempo de llenado de un molde de inyección de plásticos basada en la metodología de modelo científico y en la simulación computacional del proceso by : Miguel Angel Rivera López
Download or read book Optimización del tiempo de llenado de un molde de inyección de plásticos basada en la metodología de modelo científico y en la simulación computacional del proceso written by Miguel Angel Rivera López and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: El presente trabajo de investigación describe una metodología para optimizar el tiempo de llenado de un molde de inyección de plásticos apoyándose en el método del Moldeo Científico y en la simulación del proceso utilizando un software comercial. Este trabajo analiza los factores más importantes que deben evaluarse para determinar el tiempo de llenado óptimo. Se describen los parámetros críticos que deben de introducirse en el programa de simulación de inyección para obtener una buena correlación entre las mediciones obtenidas en la máquina de inyección y la simulación. Los experimentos usando el método del Moldeo Científico se realizaron utilizando un equipo de adquisición de datos DARTPAK conectado a una máquina de inyección DEMAG ERGOTECH para leer la presión y velocidad de inyección y posición del husillo. Las simulaciones fueron realizadas en CADMOULD. Se propone, con base en dichos experimentos y simulaciones una metodología para optimizar el tiempo de llenado basada en inferencias sobre las propiedades y condiciones del plástico dentro del molde. Dicha metodología utiliza a) la temperatura del frente de flujo, b) el esfuerzo de corte, c) la velocidad de corte y d) una curva de la resistencia al flujo (estimador de la viscosidad aparente) vs. el recíproco del tiempo de llenado (estimador de la velocidad de corte). Los experimentos y las simulaciones se hicieron utilizando un molde de tres placas de cuatro cavidades. La pieza es un engrane de uso automotriz de Nylon 4/6. Utilizando un coeficiente de correlación estadístico se encontró una correlación entre la simulación y los resultados obtenidos en la máquina de inyección del 97%. Se encontró que la temperatura mínima de frente de flujo, el máximo esfuerzo de corte y la máxima velocidad de corte obtenidas en la simulación computacional tienden a estabilizarse en el mismo tiempo de llenado en que se estabiliza la resistencia al flujo encontrada en las pruebas en la máquina de inyección y la resistencia al flujo encontrada en la simulación computacional. El uso de la metodología propuesta beneficiará al diseñador de moldes al poder reproducir el Moldeo Científico en una simulación y permitirle evaluar el diseño del sistema de alimentación y pieza desde antes de fabricar el molde, reduciendo así el costo asociado a pruebas en moldes nuevos.

Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Book Synopsis Geothermal Water Management by : Jochen Bundschuh
Download or read book Geothermal Water Management written by Jochen Bundschuh and published by CRC Press. This book was released on 2018-03-12 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Availability of and adequate accessibility to freshwater and energy are two key technological and scientific problems of global significance. At the end of the 20th century, the deficit of water for human consumption and economic application forced us to focus on rational use of resources. Increasing the use of renewable energy sources and improving energy efficiency is a challenge for the 21st century. Geothermal energy is heat energy generated and stored in the Earth, accumulated in hydrothermal systems or in dry rocks within the Earth’s crust, in amounts which constitute the energy resources. The sustainable management of geothermal energy resources should be geared towards optimization of energy recovery, but also towards rational management of water resources since geothermal water serves both as energy carrier and also as valuable raw material. Geothermal waters, depending on their hydrogeothermal characteristics, the lithology of the rocks involved, the depth at which the resources occur and the sources of water supply, may be characterized by very diverse physicochemical parameters. This factor largely determines the technology to be used in their exploitation and the way the geothermal water can be used. This book is focused on the effective use of geothermal water and renewable energy for future needs in order to promote modern, sustainable and effective management of water resources. The research field includes crucial new areas of study: • an improvement in the management of freshwater resources through the use of residual geothermal water; • a review of the technologies available in the field of geothermal water treatment for its (re)use for energetic purposes and freshwater production, and • the development of balneotherapy. The book is aimed at professionals, academics and decision makers worldwide, water sector representatives and administrators, business enterprises specializing in renewable energy management and water treatment, working in the areas of geothermal energy usage, water resources, water supply and energy planning. This book has the potential to become a standard text used by educational institutions and research & development establishments involved in the geothermal water management.
