In the first part of thesis, we had started by the estimation of the Algerian solar radiation potential. Because the use of parabolic trough solar collectors implies that these systems only work with the direct normal ...

The Bayesian approach is a statistical method; it allows trend studies on the behavior of materials between periods or after a break in the life of these materials. It naturally includes consideration of information partially ...

Magnesium hydride is the best candidate for the reversible hydrogen storage in atomic form. Indeed, thanks to its high specific storage capacity, abundance and lower prices compared with other metal hydrides, it will be ...

Heat and mass transfer are frequented in nature and industry: metallurgy, drying process, thermal isolation, and solar energy storage. In this study, convection heat and mass transfer in fluid medium are numerically studied ...

Knowledge of the failure behavior of sandwich materials, including the study of the processes leading to it is very important due to the increasing use of these materials under more and more arduous conditions. The objective ...

In this study, we are interested by the two-dimensional numerical simulation of turbulent mixed convection in a ventilated square cavity. The cavity is equipped with a slot entrance located in the bottom left corner and a ...

Our study concerns the tribological behavior of bronze-graphite, copper-graphite and graphite-graphite couples in a dry sliding contact with and without electrical current. We conducted experimental trials to determine the ...

In this study we have used dimethylphenols (xylenol) as models pollutants to show the effectiveness of the natural hematite (Fe2O3 natural) on the photocatalytic processes in heterogeneous environment. The degradation of ...

This thesis presents a numerical simulation of the forced convection in a horizontal channel contained identical heated blocks with uniform and pulsation flow in the entrance of the channel. We examined two applications: ...
