    NUMERICAL MODELING OF A PARABOLIC TROUGH SOLAR COLLECTOR AT BOUZARÉAH, ALGERIA
    (جامعة الوادي - university of el oued, 2015) Ghodbane, M; Boumeddane, B
    In this paper, we are interested in numerical study conversion of the solar energy into thermic energy using a Parabolic through Collector at Bouzaréah, Algeria. Water is used as a heat carrier fluid. A mathematical model drawn from the energy balance equation applied to the absorber tube, it was solved by the finite difference method. A computer program was developed to solve our problem. MATLAB used as a tool for simulation. This program allows calculating the change in thermal efficiencies, the absorber tube temperatures, the fluid temperatures, the glass temperatures and the coefficient of heat loss. The results are very honorable and encouraging, where the thermal efficiency of the concentrator had passed 60%.

    STUDY OF BOIL- OVER PHENOMENON, THE ALGERIAN. PETROLEUM AS A MODEL FOR INSPECTION
    (جامعة الوادي - university of el oued, 2015) Ghodbane, M
    With the development of oil facilities, development of industrial security and evolved methods of preventionn but industrial risks always remain present. In this work, we we'll examine a very serious phenomenon, which “Boil-Over”. This phenomenon appears in petroleum reservoirs (oil has a high viscosity), and that in the event of a fire on the roof of the tank with the presence of water at the bottom of the tank. We chose the Algerian Petroleum to conduct this study. We will talk to the disastrous results of this phenomenon, and risks to all people, equipment and the environment.
