This paper presents an analysis of the effect of two synthetic antioxidants on
the vaporization processes of coconut and linseed oils for fuel use. Several
studies agree on the effectiveness of synthetic or natural antioxidants against
the polymerization of vegetable oils. The principle of action of the latter is to
increase the rate o(...)

Determination of the Performance Scores of a Photovoltaic Power Plant Connected to the Grid: The Zagtouli Photovoltaic Power Plant in Burkina-Faso
Toussaint Tilado Guingane, Éric Korsaga, Sosthène Tassembedo, Rene Ouedraogo
Photovoltaic solar energy is still in its infancy in Burkina Faso, despite the country’s high solar potential. The electricity grid is experiencing an increase in demand for energy, creating a shortfall in supply. The Zagtouli photovoltaic solar power plant in Burkina Faso is the first milestone in the development of renewable photovoltaic ene(...)

Modeling the Influence of Raleigh Numbers on Thermal and Fluidic Behaviors in a Trapezoid-shaped Cell
Windé Nongué Daniel Koumbem, Bouwèreou Bignan-Kagomna , Noufou Bagaya , Wend Dolean Arsène Ilboudo, Pare Daouda, Issaka Ouédraogo, Sié Kam
We model the influence of Raleigh numbers in a trapezoidal cavity. One wall among the sloping walls is exposed to a heat flux density Q=100 W/ m2 and the other inclined wall is kept adiabatic. The temperature of the two horizontal walls is assumed to be constant such that Tsup=305K is greater than Tinf=300K. The equations of heat and mass tran(...)

Study of the thermo-physical parameters of wood using a calorimeter cone
Baguian Abdoul Fayçal, Lingani Abdel Kader Hounsouho, Dabilgou Téré, Ye Siedouba Georges, Zaida Justin, Kam Sié, Ouiminga Koucka Salifou, Bere Antoine
Our study involves characterizing the thermo-physical parameters of materials found in habitats, to understand their degradation mechanisms. It has shown that the mechanical and physical properties of wood are dependent on many factors such as density or heat source, which can be influential and easier or harder to quantify.

Design and Experimental Study of a Hemispherical Solar Cooker: Application to Food Cooking
Bouto Kossi Imbga, Ladifata Mogmenga, Thierry Sikoudouin Maurice Ky, Kaloukri Ouena and Sié Kam
The present work is an experimental study of a glazed hemispherical solar cooker. It consists of a hemispherical concentrator made of reinforced concrete with a smooth inner part lined with a self-adhesive aluminium mirror film with a reflectivity of 95%. This reflector enables all the sun rays to be reflected onto the absorber. The hemisphere(...)
