Item MODÉLISATION ET RÉSOLUTION NUMÉRIQUE DE L'ÉQUATION DE POISSON EN 2D PAR LA MÉTHODE DE DIFFÉRENCE FINIE CAS DE L'ÉQUATION DU TRANSFERT DE LA CHALEUR(جامعة الوادي - university of el oued, 2012) Benhissen, N; Khechekhouche, AThe objective of this work is to solve the Poisson equation by the finite difference method is therefore to provide an approximate solution of the actual behavior of a physical phenomenon. Such as the equation of heat transfer. We will take as a model of square/rectangular plate, with different boundary conditions and we will specify also the values boundaries (the Dirichlet condition). The analysis is based on the simulation results based on certain criteria and choice of parameters that comes into play in the equation, this will give us a good understanding of the manipulation of these parameters and thus understand what is happening on environment studiedItem Seasonal effect on solar distillation in the El-Oued region of south-east Algeria(Seasonal effect on solar distillation in the El-Oued region of south-east Algeria, 2017-07-27) Khechekhouche, A; Boukhari, A; Driss, Z; Benhissen, NIn the present purely experimental work, we tested a solar distiller with a simple slope in the region of El-Oued located in the south-east of Algeria, during the winter then the summer seasons at the same place. Dimensions of the studied device are 1000 x 500 mm, while the depth of the water to be distilled is 1 cm, the glazing thickness is 4 mm, and the tilt angle with respect to the horizontal is 10 °.The aim of this work is to compare distillation between winter (January) and summer (May) to show that weather factors such as solar radiation, ambient temperature and humidity are influential on the distiller productivity. The amount of distilled water in winter was about 119 ml per day. However, that in summer was 1127 ml per day in total, so it is an increase of more than 9 times the production of distilled water.
