Book excerpt: LE TRAVAIL PRESENTE DANS CE MEMOIRE CONCERNE L'ETUDE DE LA FORMATION ET DE LA CROISSANCE D'UNE PHASE GAZEUSE PAR DECOMPRESSION D'UN LIQUIDE SURSATURE EN GAZ AU SEIN D'UN MILIEU POREUX. LA MAITRISE DE CETTE SITUATION, QUI SE RENCONTRE LORS DE L'EXPLOITATION DE CERTAINS GISEMENTS DE PETROLE OU GEOTHERMIQUES, EST TOUT A FAIT CAPITALE POUR TRAITER CONVENABLEMENT LES HISTORIQUES DE PRODUCTION DE MASSE OU D'ENERGIE. INSCRIT DANS LA CONTINUITE DES ETUDES ANTERIEUREMENT DEVELOPPEES SUR LE SUJET AU SEIN DE L'INSTITUT DE MECANIQUE DES FLUIDES DE TOULOUSE, LE PRESENT TRAVAIL S'EFFORCE DE REPONDRE A DEUX OBJECTIFS: PREMIEREMENT, COMPLETER L'INVESTIGATION EXPERIMENTALE DEJA EFFECTUEE, EN UTILISANT UNE GAMME PLUS LARGE DE SOLUTIONS, AFIN D'EVALUER NON SEULEMENT L'INFLUENCE DU NOMBRE DE JACOB ET DU TAUX DE DECOMPRESSION MAIS EGALEMENT DE LA MOUILLABILITE ET DE LA GRAVITE SUR LES PHENOMENES ETUDIES, DEUXIEMEMENT, PROPOSER DES MODELES DE SIMULATION NUMERIQUE OFFRANT DES POSSIBILITES D'ANALYSE ET DE PREDICTION AUSSI BIEN DE LA FORMATION DE LA PHASE GAZEUSE (NUCLEATION) QUE DE SA CROISSANCE. POUR DEVELOPPER CE PROGRAMME, EN L'OCCURENCE LIMITE A LA CONFIGURATION 2D (AFIN DE POUVOIR ASSOCIER AUX DONNEES QUANTITATIVES DES OBSERVATIONS PHENOMENOLOGIQUES) ET AUX REGIMES PRINCIPALEMENT CONTROLES PAR LA CAPILLARITE ET LA DIFFUSION MOLECULAIRE (AFIN D'EVITER LA COMPLEXITE DU COUPLAGE DES PHENOMENES HYDRODYNAMIQUES ET MASSIQUES DANS LA SIMULATION NUMERIQUE) DIFFERENTS MOYENS METHODOLOGIQUES ONT ETE ADAPTES, DEVELOPPES ET EVALUES. CES MOYENS CONCERNENT: DU POINT DE VUE EXPERIMENTAL: L'IMPLANTATION D'UN SYSTEME D'ACQUISITION ET DE TRAITEMENT D'IMAGES PERMETTANT LE SUIVI INSTANTANE DE L'APPARITION DES BULLES DE GAZ ET DE LEUR CROISSANCE, DU POINT DE VUE NUMERIQUE: LA CONCEPTION D'UN AUTOMATE PERMETTANT DE REPRODUIRE LA LOCALISATION SPATIALE DES SITES DE NUCLEATION ET SURTOUT LA CROISSANCE DES AMAS GAZEUX. OUTRE LA CONFIRMATION DES MECANISMES DE FORMATION DE LA PHASE GAZEUSE: PREEXISTENCE DE BULLES, PIEGEAGE CAPILLAIRE, ACTIVATION SEQUENTIELLE DES SITES ET CROISSANCE PAR DIFFUSION, LES RESULTATS EXPERIMENTAUX ONT PERMIS DE DISTINGUER ET DE QUANTIFIER LES CONSEQUENCES DE LA SURSATURATION DU MOUILLAGE ET DE LA GRAVITE SUR LA CROISSANCE DE LA PHASE GAZEUSE. LES LOIS OBTENUES SONT TRES DIFFERENTES DE CELLES CONNUES HORS MILIEU POREUX. COMME L'INDIQUE L'ETUDE DE CERTAINS FACTEURS GEOMETRIQUES, ISSUS DE L'ANALYSE D'IMAGES, CES DIFFERENCES SONT FORTEMENT CORRELEES AVEC L'EVOLUTION SPECIFIQUE DE L'AIRE INTERFACIALE, GAZ-LIQUIDE, AU SEIN DE LA MICROSTRUCTURE. LA SIMULATION DU PROCESSUS DE CROISSANCE D'UN AMAS GAZEUX ET D'ENVAHISSEMENT DU MILIEU POREUX A ETE EFFECTUEE A L'AIDE D'UN AUTOMATE NUMERIQUE CONSTRUIT A PARTIR DES OBSERVATIONS, ANALYSES ET INTERPRETATIONS DES PHENOMENES A L'ECHELLE DES PORES.

Book excerpt: LE TRAVAIL PRESENTE DANS CE MEMOIRE CONCERNE L'ETUDE DE L'APPARITION DE BULLES DE GAZ PAR DECOMPRESSION D'UN LIQUIDE EN MILIEU POREUX MODELE (MICROMODELE). CETTE SITUATION SE RENCONTRE LORS DE L'EXPLOITATION DE CERTAINS GISEMENTS PETROLIERS OU GEOTHERMIQUES. LES OBJECTIFS PRINCIPALEMENT VISES SONT: L'ANALYSE DES MECANISMES QUI GOUVERNENT LA NUCLEATION DES BULLES ET LEURS CROISSANCES ET L'EVALUATION DES POSSIBILITES OFFERTES PAR CERTAINS MODELES POUR PREDIRE LA CINETIQUE DE PRODUCTION. L'OBSERVATION DES SITES DE NUCLEATION, LE NOMBRE DE BULLES ET LEUR CINETIQUE DE CROISSANCE EN FONCTION DE LA CHUTE DE PRESSION, PERMETTENT DE PROPOSER UN MECANISME DE FORMATION DE LA PHASE GAZEUSE SIMILAIRE A CELUI OBSERVE LORS DE L'EBULLITION D'UN LIQUIDE SUR UNE PAROI RUGUEUSE. IL EST CONSTITUE DE 4 ETAPES: NUCLEATION HETEROGENE OU PREEXISTENCE DE MICROBULLES, CROISSANCE ET PIEGEAGE CAPILLAIRE DANS DES RUGOSITES, ACTIVATION D'UNE FRACTION DES SITES ET CROISSANCE DES BULLES PAR DIFFUSION. LES 3 PREMIERES ETAPES SONT QUASI INSTANTANEES, QUANT A L'ETAPE DE DIFFUSION ELLE CONTROLE LE TEMPS DE CROISSANCE DE LA BULLE JUSQU'A L'ECHELLE D'OBSERVATION. LES EXPERIENCES DE CROISSANCE D'AMAS PAR DIFFUSION ET EXPANSION ONT PERMIS DE DEGAGER: LE ROLE ET L'IMPORTANCE RELATIVE DU NOMBRE DE BULLES (AIRE INTERFACIALE), LA BONNE PRODUCTIBILITE DES PHENOMENES QUI CONTROLENT LE DEVELOPPEMENT DU VOLUME GAZEUX CONFIRMANT EN OUTRE L'EVOLUTION VERS UNE STRUCTURE DU TYPE PERCOLATION, LE SUCCES RELATIF D'UN MODELE FONDE SUR L'HYPOTHESE DE MICROBULLES PIEGEES (MODELE DE YANG) POUR INTERPRETER LES EXPERIENCES A TAUX DE DECOMPRESSION DONNE

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.
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.
