Ce travail est l'étude expérimentale de la distribution de la température en fonction du temps pour deux différents matériaux ferromagnétique (Acier) et amagnétique (Aluminium), afin de faciliter la résolution analytique de l'équation différentielle…

In this work, we study numerically mixed convection flows in an open U-shaped channel. The right opening lets pass fresh air at cold temperature TC, while the walls of the channel are heated at the temperature TH > TC. Our study is based on a…

This paper present novel approach for traction control of four wheel electric propulsion system for each wheel. This algorithm is necessary to improve the vehicle safety, the independent Machine Control philosophy is employed using an intelligent…

Chad has done the study and development of renewable resources a priority in its energy mix. Wind energy is one of the renewable sources that can help Chad to develop rural areas and preserve the environment. This study presents from data obtained…

Solar panels have a nonlinear voltage-current characteristic, with a distinct maximum power point (MPP), which depends on the environmental factors, such as temperature and irradiation. In order to continuously harvest maximum power from the solar…

Le traitement des sols permet d’améliorer les caractéristiques d’un sol, afin de le rendre apte à supporter une chaussée, sans avoir de gros travaux. Dans le domaine du Génie Civil, l’étude des sols est la première étape de l’étude pour développer un…

The problem of stabilizing a boost converter in small-signal situations using linear control laws is derived by the means of oriented circuit procedure. After establishing a small-signal circuit model for the boost regulator including state-feedback,…

For decades, hydropower has been the most important renewable energy source in the world. The use of Banki-Michell turbine (B-M) in small hydropower constitutes an attractive solution for rural electrification in developing countries and off-grid…

Cavitation is a physical phenomenon that often occurs in hydraulic machines such as pumps, valves, and turbines. Although the Banki-Michell turbine has been used for a long time in small hydropower, no study related to this phenomenon of cavitation…

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…
