Public ISBD Titre : Optimisation et modelisation d’un distillateur solaire a ailettes avec stockage de chaleur Type de document : texte imprimé Auteurs : Nafila Smakdji, Auteur ; Abdenacer Kaabi, Directeur de thèse Editeur : constantine [Algérie] : Université Constantine 1 Année de publication : 2014 Importance : 137 f.

Index. décimale : 626 Génie Climatique Résumé : To improve the efficiency of simple solar still greenhouse, several experimental work has been made, specifically, active solar still which is a simple solar still coupled with a solar collector where the brine distillation is preheated. To increase the amount of distilled water we studied an active solar still modified with a sensible heat storage tank. Our prototype consists of a simple solar still consisting of a metallic cover which acts as the condenser. A type 'tube' heat exchanger is installed inside the still to heat the brine, a good insulation has been planned at the level of the posterior part of the solar still . As the performance of it is strongly influenced by the temperature difference between brine and coverage of the solar still , with cooling fins are placed on the outside of the cover. Our study we are seeing a significant improvement in the daily production. Our present work is aimed to enrich existing data by mathematical modeling of our prototype based on appropriate heat balances and the use of heat and mass coefficients, with some simplifying assumptions. The purpose of numerical simulation is the optimization of the parameters that affect the production of distilled water, giving an order of magnitude of what thermal storage can make to the proper functioning of a simple solar still Diplôme : Doctorat en sciences En ligne : ../theses/gclim/SMA6659.pdf Format de la ressource électronique : pdf Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9954 Optimisation et modelisation d’un distillateur solaire a ailettes avec stockage de chaleur [texte imprimé] / Nafila Smakdji, Auteur ; Abdenacer Kaabi, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2014 . - 137 f. ; 30 cm. 2 copies imprimées disponibles Langues : Français (fre) Tags : stockage thermique  énergie solaire  eau saumâtre  distillation solaire  ailettes  écart de température  thermal storage  solar energy  brackish water  Solar distillation  fins  temperature difference  ????? ?????  ???? ?????  ????? ????  ?????  ???? ???? ???????
