Influence of Construction Materials and Building Orientation on Building Thermal Load in Hot and Dry Tropical Climate
Ousmane Coulibaly , Frederic Kuznik , Dominique Baillis and Abdoulaye OuedraogoAbstract: This paper is concerned with the determination of the thermal energy performances of individual houses built with “H” shape bricks in hot and dry tropical climate (different cities of Burkina Faso and the city of Bamako in Mali). The bricks’ matrices include three void spaces...

Modelling Study of Magnetic Field’s Effects on Solar Cell’s Transient Decay
Senghane Mbodji, Martial Zoungrana, Issa Zerbo, Biram Dieng, Gregoire SissokoExperimental setup of transient decay which occurs between two steady state operating points is recalled. The continuity equation is resolved using both the junction dynamic velocity (Sf) and back side recombination velocity (Sb). The transient excess minority carriers density appears as the sum...

A 3D Modelling of Solar Cell’s Electric Power under Real Operating Point
Mayoro Dieye, Senghane Mbodji, Martial Zoungrana, Issa Zerbo, Biram Dieng, Gregoire SissokoThis work, based on the junction recombination velocity (Sfu) concept, is used to study the solar cell’s electric power at any real operating point. Using Sfu and the back side recombination velocity (Sbu) in a 3D modelling study, the continuity equation is resolved. We determined the...

Influence of chemical potential on water transport in a hygroscopic soil
Samuel Ouoba, Fabien Cherblanc, Jean-Claude Bénet, Jean KoulidiatiConcerning the description of mass transport in a porous media, particularly in soil, the question is to know what are the main mechanisms to consider during transport phenomena for a best description of these transports. The answer to this question requires good understanding on thermodynamic...
