Le développement des techniques et la prise de conscience des problèmes énergétiques et d’environnement concourent à un nouvel essor de cette source d’énergie. Son intérêt est d’autant plus grand que les sources traditionnelles industrielles sont éloignées, que l’habitat est distribué, et que les investissements liés à l’établissement d’un réseau de distribution sont plus élevés. La principale barrière à son développement terrestre a longtemps été le coût élevé des photopiles. Le panneau solaire à base de silicium fournit de l’électricité à 5FF le kW/h. Les recherches sur de nouvelles structures au silicium et sur de nouveaux matériaux permettent d’envisager de meilleurs rendements pour une fiabilité et des coûts attractifs.

Très riche en biométhane, ce gaz permet l’approvisionnement énergétique renouvelable notamment des zones agricoles et rurales où la biomasse organique est abondante. Dans ce contexte, la Division Biomasse prospecte la filière de la production du biogaz à partir des déchets organiques qui reste une source énergétique non exploitée en Algérie. L’article proposé présente une première approche de cette prospection qui consiste en l’installation d’un digesteur expérimental d’une capacité de 800 litres. Son utilisation pour une première biométhanisation mésophile a permis de produire 26,898 m3 de biogaz à partir de 440 Kilogrammes de bouses de vaches durant 77 jours. La composition moyenne du biogaz est de 61% de méthane et de 35,65% de gaz carbonique.

Outre les valeurs moyennes, les fluctuations turbulentes ainsi que leurs corrélations représentent des grandeurs essentielles pour comprendre et tenter de modéliser les mécanismes de transfert. Un choix judicieux des instruments est critique pour une bonne mesure de ces grandeurs. Le premier critère de choix des instruments de mesure porte donc sur une meilleure réponse en fréquence. Un second critère important est lié à la taille des sondes qui doit être la plus réduite possible de façon à limiter les perturbations apportées à l’écoulement. A ces deux considérations s’ajoute une troisième, plutôt d’ordre pratique, qui consiste en un bon choix des surchauffes appliquées aux éléments de la sonde. Dans le présent cas, le fil, élément amont, est nettement plus chauffé que le film aval. Pour cette configuration de surchauffes, les isoconcentrations sont des droites clairement dissociées. Ce mode de fonctionnement permet d’étendre notamment la gamme de vitesses accessibles aux mesures pour des mélanges allant de l’air à l’hélium purs.

Le logiciel prédit les flux de chaleur échangés dans une fourchette de 10%. L'échangeur croisé contre-courant est le plus performant des échangeurs croisés. La configuration croisée simple est non rentable. Dans la plupart des cas, le flux de chaleur total échangé par un échangeur croisé contre-courant est environ de 10% supérieur au flux échangé dans un échangeur croisé cocourant.

The estimation of fatigue for a rotating blade must go through several steps of calculation: among them the calculation of mode shapes and frequencies and the computation of displacements and stresses acting on the blades. In this work two methods are used in the calculation of the mode shapes, the first one is based on the discretization of the blade element, whereas the second method is based on the resolution of the differential equation of the blade as a continuous system. This later method is more advantageous in determining mode shapes as well as stresses acting on the blades because it doesn’t require the use of a powerful computer. Once the stresses are calculated, the fatigue is estimated using the theory of « cumulative damage in fatigue ». This estimation must be based on the statistical distribution of wind speed for the site in use.
