    Effect of Rubber Thickness on the Performance of Conventional Solar Stills under El Oued city climate (Algeria)
    (جامعة الوادي Université ofEl-Oued, 2023-04-03) Kermerchou, Imad; Khechekhouche, Khechekhouche; Elsharif, Nabil
    Our study focuses on examining the performance of conventional solar stills in an arid region, specifically investigating the impact of rubber material and its thickness on the distillation process. Four solar stills were tested, including a reference solar still (SSR) and three modified solar stills (MSS1, MSS2, and MSS3) with rubber thicknesses of 1 cm, 2 cm, and 3 cm, respectively. The experimental findings clearly demonstrate a notable difference in distilled water productivity between varying rubber thicknesses. The outputs of MSS1, MSS2, and MSS3 were measured at 1105 ml/day, 1010 ml/day, and 955 ml/day, respectively, all surpassing the output of SSR, which was recorded at 830 ml/day. These results indicate that the utilization of rubber with varying thicknesses positively impacts the productivity of the solar still, leading to higher distilled water yields compared to the reference configuration

    The profile of the electric field on the earth discontinuity with a lightning conductor
    (جامعة الوادي - university of el oued, 2016-12-31) Khechekhouche, Khechekhouche
    In this paper, we present some results of investigations carried out in the electric field distribution of both horizontal and vertical lightning conductors in the case of discontinuous earth. The conductors may be situated as well as in the upper or the lower earth part. The electric field distribution was determined in the case of lightning conductor situated between the high voltage rod and the discontinuity (interface) and also in the case of high voltage rod situated between the lightning conductor and the discontinuity. In some situations the electric field distribution on the plan are smaller than defined by the electro-geometrical model. We attribute this result to the great field intensity at the discontinuity, which reduce the lightning conductor discharge capture effect. This is in concordance with the results concerning the electrical strength of such air gaps without lightning conductors
