This paper proposes a control method for the maximum power point tracking (MPPT) of a photovoltaic system and this with the aim of increasing the output power of a photovoltaic system. An electronic controller is built-in between the photovoltaic…

Our energy future must be based on non-polluting energies with significant resources. Renewable energies are the best candidates, but the intermittency of their production requires finding efficient and environmentally friendly storage means. Solar…

The need to produce a better quality product for sale to the cotton textile mills and to reduce labour costs during processing has led to considerable interest in machinery optimization concepts for cotton module builders and gins. Commercial module…

Comme tout processus industriel, un système photovoltaïque peut être soumis, au cours de son fonctionnement, à différents défauts et anomalies conduisant à une baisse de la performance du système et voire à son indisponibilité. Permettre de…

In Madagascar, the drying of Curcuma consists of exposing them directly to the Sun. This is not always productive. This work aims to provide information on the drying of turmeric by determining the drying curve in order to consider industrial drying.…

Nous déterminons le coefficient de diffusion globale de masse de cinq bois tropicaux (ayous, iroko, lotofa, sapelli et fraké) venus du Cameroun. Pour cet effet, les cinétiques de séchage issues d’un séchoir solaire et d’un séchoir conventionnel sont…

This experimental study and mathematical modelling aim to improve the heat transfer by convection in different cases of transversal baffles inside a duct of a solar air collector. The study enabled us to formulate a mathematical equation of the heat…

One of the most delicate parts to size in a water pumping windmill is the pump rod. Indeed, frequent ruptures during the exploitation and experimentation of windmills shows that the determination of the real forces acting on the pump rod is quite…

The knowledge of wave energy propagation in the shallow water allow us to understand the functioning of marine ecosystems and to give answers about several costal phenomena. In the Algerian coast, the waves are omnipresent with an energy that is…

Solar energy can be used for substitution of the depleting fossil fuels in thermal applications and electricity generation through thermal route. For medium and high temperature applications, a system for collecting solar energy at high temperatures…
