Book excerpt: Améliorer l'efficacité énergétique des bâtiments et limiter l'ilot de chaleur urbain est une priorité, en particulier dans les centres-villes historiques, composés de bâtiments peu isolés. Un des leviers d'action envisagés est l'isolation des parois. Cependant, la rénovation des parois anciennes rencontre de nombreux obstacles (technologiques, architecturaux, urbains). Ces parois ont notamment un comportement hygrothermique spécifique, qu'il convient de prendre en compte pour éviter l'apparition de pathologies et estimer correctement les déperditions énergétiques. Il est donc primordial d'intégrer les transferts hygrothermiques à travers les parois pour simuler efficacement le bâti ancien. Néanmoins, la plupart des modèles à l'échelle urbaine négligent les transferts hydriques à travers les parois.Cette thèse propose une nouvelle méthode de résolution numérique pour les transferts hygrothermiques, qui est adaptée aux différentes contraintes de la modélisation à l'échelle urbaine (résolutions spatio-temporelles, méthode numérique etc.). La validation est réalisée en deux temps : une partie numérique et une partie expérimentale. La validation numérique est effectuée par une comparaison inter-modèle, en s'appuyant sur quinze compositions de parois et trois climats. La validation expérimentale utilise les données enregistrées dans plusieurs bâtiments rénovés à partir de matériaux biosourcés et instrumentés dans le centre médiéval de la ville de Cahors.Ensuite, les transferts couplés de masse et de chaleur dans les parois sont intégrés dans le modèle de climat urbain TEB (Town Energy Balance), en utilisant la méthode développée et validée. La pertinence de cette nouvelle version de TEB pour représenter le centre-ville médiéval de Cahors est évaluée par comparaison avec des mesures in-situ. Une amélioration significative est constatée pour la simulation de l'humidité relative intérieure. L'impact des transferts d'humidité est discuté à plusieurs échelles.Finalement, la réhabilitation des parois anciennes des bâtiments du centre-ville de Cahors est étudiée à partir de plusieurs types d'isolant thermique positionnés à l'intérieur ou à l'extérieur. Ces scénarios de réhabilitation sont simulés en utilisant la version modifiée de TEB incluant les transferts d'humidité à travers les parois. Leur pertinence est comparée, vis-à-vis des enjeux énergétiques, du confort intérieur et extérieur, de la conservation du patrimoine et de la durabilité des parois. Des recommandations sont formulées en fonction du type de parois.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ces travaux de thèse s'inscrivent dans le cadre du projet ANR HUMIBATex « Comment prédire les désordres causés par l'humidité ? Quelles solutions techniques pour rénover le bâti existant ? » (2012-2016). Elle traite de la modélisation numérique et expérimentale des transferts couplés hydro-thermo-aérauliques à différentes échelles : matériau, paroi et ambiance de bâtiment. Sur le plan théorique, un modèle phénoménologique des transferts couplés de chaleur, d'air et d'humidité à travers les enveloppes de bâtiments (HAM) a été élaboré. Après la phase de validation (confrontation avec des solutions analytiques et des résultats expérimentaux), ce modèle a été implémenté avec confiance dans un code de simulation thermique dynamique du bâtiment (BES). Ceci a permis, ainsi, de développer une plateforme de co-simulation HAM-BES. Grâce à l'outil mis en œuvre, les comportements hygrothermiques de la paroi et de l'ambiance habitable des bâtiments ont été prédits finement. Deux cas d'études ont été entrepris. Le premier avait pour but de mettre en évidence l'impact des transferts hygrothermiques sur la prédiction des consommations énergétiques. Le deuxième cas d'étude a été dédié à l'étude de l'efficacité de différentes stratégies de ventilation (extraction ou insufflation) sur le contrôle et la diminution des risques d'apparition de désordres liés à l'humidité au niveau des bâtiments résidentiels. Sur le plan expérimental, une campagne de caractérisation des propriétés physiques, hydriques et thermophysiques des matériaux de construction a été effectuée. Cette campagne expérimentale s'est focalisée sur l'analyse de l'impact de l'état thermique et hydrique du matériau sur les valeurs des propriétés hygrothermiques. Dans un autre travail expérimental, des dispositifs expérimentaux, à petite échelle mais également à l'échelle de la paroi, ont été conçus au laboratoire dans le but d'étudier la réponse hygrothermique des enveloppes de bâtiment ainsi que valider la plateforme de co-simulation dynamique HAM-BES. La confrontation des résultats a montré une bonne concordance entre la résolution numérique et les mesures expérimentales. Les résultats obtenus dans le cadre de ce travail de thèse ont mis en exergue l'influence d'une modélisation fine des transferts couplés de chaleur, d'air et d'humidité, à la fois sur la prédiction du comportement hygrothermique des ambiances habitables mais aussi sur le calcul des besoins énergétiques des bâtiments.

Book Synopsis Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Synopsis Fluorine Magnetic Resonance Imaging by : Ulrich Flogel
Download or read book Fluorine Magnetic Resonance Imaging written by Ulrich Flogel and published by CRC Press. This book was released on 2016-10-26 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, fluorine (19F) magnetic resonance imaging (MRI) has garnered significant scientific interest in the biomedical research community owing to the unique properties of fluorinated materials and the 19F nucleus. Fluorine has an intrinsically sensitive nucleus for MRI. There is negligible endogenous 19F in the body and thus there is no background signal. Fluorine-containing compounds are ideal tracer labels for a wide variety of MRI applications. Moreover, the chemical shift and nuclear relaxation rate can be made responsive to physiology via creative molecular design. This book is an interdisciplinary compendium that details cutting-edge science and medical research in the emerging field of 19F MRI. Edited by Ulrich Flögel and Eric Ahrens, two prominent MRI researchers, this book will appeal to investigators involved in MRI, biomedicine, immunology, pharmacology, probe chemistry, and imaging physics.

Book Synopsis How to Design Wastewater Systems for Local Conditions in Developing Countries by : David M. Robbins
Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
