    Energy recovery from the treatment water plant of Lakhdaria for electricity production
    (2019) Iguercha, Amina; Ferhat, B.; Mohammedi, K.; Bouaziz, M.
    he water that reaches our taps follows a path represented by the pipelines. It must be supplied with energy so that it can circulate along the pipeline, which therefore creates a link between energy and water. Water treatment plants in Algeria consume electrical energy for its pumping and lighting systems. The objective of this work is the study of feasibility of recovering energy at loads breezes which are generally installed on the field to break the water pressure to the reservoir. This gives an opportunity for innovation in the water sector, bringing water and energy without Co2 emissions and with inexhaustible energy and economic able to provide hydroelectric power almost continuously.

    Étude de préfaisabilité du turbinage des eaux de la station de traitement de Koudiet Acerdoune/Algérie
    (Mouloud Mammeri University of Tizi-Ouzou, 2022) Iguercha, Amina; Zouaoui, S.; Mohammedi, K.; Bouaziz, M.; Kari, D.
    Cette étude vise à récupérer l'énergie résiduelle de l’eau à son arrivée dans la station de traitement d'eau par turbinage, au lieu de continuer à la dissiper comme on le fait actuellement au moyen de robinets brises-charge. Une analyse de la faisabilité technique du projet et une évaluation du potentiel hydroélectrique disponible ont été accomplies, avant de proposer différentes options pour l’installation des équipements de turbinage. En utilisant cette méthode, le maximum de quantité d'énergie qui peut être récupérée a été estimée à 7,44 GWh, celui de la quantité de carbone économisée a été estimé à 446,210 tonnes CO2. Nous concluons notre projet par une évaluation de la rentabilité des aménagements hydroélectriques.

    Modeling of interference fits taking form defects of the surfaces in contact into account
    (Elsevier, 2011) Boutoutaou, Hamid; Bouaziz, M.; Fontaine, J.F.
    The technique of assembly by shrink fit is increasingly used today. However, the methodology of parts sizing has not changed in 50 years. Assembled parts are assumed to have accurate dimensions and very low form defects. This has the disadvantage of increasing the cost of parts production. To reduce manufacturing costs, the study of the influence of form defects on the characteristics of assembly strength is essential. Taking default form into account assumes that the tightening (difference between the diameters of the shaft and the bore) is defined. In the case under consideration, the tightening depends locally on the radius. Two definitions of the tightening are proposed: maximum tightening and mean tightening. It is shown that the form defect is not detrimental to the assembly strength: the mean pressures are nearly equivalent to the classical case of surfaces without defects. Various finite element simulations were performed. The influence of the value and the type of defect have been studied for conventional tightening (elastic materials) and more intensive tightening (elasto-plastic behavior) in the case of axisymmetrical and non-axisymmetrical parts. The theoretical results correlate well with those obtained through experiments. However, for intensive tightening, the behavior of the roughness is not negligible
