Evaluation of Water Losses by Evaporation in the Nakanbe Basin
Bayala Alfred, Kabre Sayouba, Yonli Hamma Fabien, Chesneau Xavier , Thierry Sikoudouin Maurice Ky, Zeghmati Belkacem , Kieno P. Florent, Kam Sié
A numerical approach to heat and mass transfer in a large water reservoir is presented. This water reservoir is likened to a parallelepiped reservoir whose vertical and lower walls are adiabatic and impermeable. The equations that govern natural convection in water are solved by the finite volume method and Thomas'salgorithm. The adequacy betw(...)

Saffron extract-mediated synthesis of Cu(OH)2 nanocomposite: Structural and photocatalytic activity investigation
Sidiki Zongo, Tongonmanegde Leonard Ouedraogo, Sié Zacharie Kam, Moussa Sougoti, Tizane Daho, Balla Diop Ngom, Malik Maaza, Jean Koulidiati & Antoine Béré
We report a green and eco-friendly route for copper hydroxide Cu(OH)2 rods-like synthesis using an aqueous extract of Saffron-assisted NaOH co-precipitation method. The structural, morphology, photodegradation, and optical properties were extensively investigated using SEM/HR-TEM, XRD, EDS, FT-IR, and UV–Vis spectroscopy. The structural analys(...)

A Vegetable Oil as Heat Transfer Fluid for Parabolic Trough Collector: Dynamic Performance Analysis under Ouagadougou Climate Conditions
Bagré, Boubou, Sié Zacharie Kam, Yomi Woro Gounkaou, Makinta Boukar, Ibrahim Kolawole Muritala, Harouna Sani Dan Nomao, Korsaga Armand, Antoine Beré, and Tizane Daho
In this study, the thermal performance of the parabolic trough collector (PTC) has been addressed under Ouagadougou climate conditions. Thus, after developing a model, the effect of mass flow on PTC performance showed that the Jatropha curcas oil (JCO) temperature difference increases when the mass flow rate (𝑚˙) decreases while the thermal ef(...)

Computational Model of Effective Thermal Conductivity of Green Insulating Fibrous Media. Materials
Sankara, H.; Baillis, D.; Coulibaly, O.; Coquard, R.; Naouar, N.; Saghrouni, Z
Modelling effective thermal properties is crucial for optimizing the thermal performance of
materials such as new green insulating fibrous media. In this study, a numerical model is proposed
to calculate the effective thermal conductivity of these materials. The fibers are considered to be
non-overlapping and randomly oriented in space. The(...)

Experimental study of the evolution of yemperature in pavement structures and influence of traffic on the RN1 in Burkina Faso in a hot and dry climate
Paul Ilboudo, Boubacar Soro, Dieudonné Dabilgou, Boureima Kaboré, Jean Marie Compaoré, Sié Kam *, Dieudonné Joseph Bathiebo
Asphalt concrete pavements in hot and dry climates deteriorate prematurely some time after their construction. This degradation is accelerated under the effect of heavy vehicle traffic pressure and high temperatures after the bitu-
men has softened. A study was conducted on the RN1 in Burkina Faso in order to analyze the evolution of temperat(...)

Dynamic Approach to the Energy Functioning of a Built Space and Associated Carbon Footprint: Application to a School Complex Located in Ouagadougou
Sawadogo, D., Coulibaly, O., Chesneau, X., & Zeghmati, B.
We propose in this study a dynamic simulation of the energy functioning of a built space in order to deduce an evaluation of the associated carbon footprint. A simulation and modeling tool is implemented based on several methodological references. We first use a systemic approach to describe the structural and functional aspects of the systems(...)

Effect of Base Thickness on the Performance of a Polycrystalline Silicon-Based Semiconductor Radial N/P Junction Solar Cell in the Static Regime under Monochromatic Illumination
Aboubacar Savadogo, Bernard Zouma, Ramatou Konate, Cyrille Constant Moyenga, Raguilignaba Sam
In this work, the importance of the base thickness on the performances of a radial n/p junction solar cell-based polycrystalline silicone is shown. Thus, from a theoretical study under monochromatic illumination in a static regime, we established new analytical expressions of electrical parameters. By simulations on Mathcad 15 software with ph(...)

Evaluation of the Performance of Lithium-Ion Accumulators for Photovoltaic Energy Storage
Toussaint Tilado GUINGANE , Dominique BONKOUNGOU, Eric KORSAGA, Dieudonné Simpore, Soumaila Ouedraogo, Zacharie Koalaga, François Zougmore
In a context of climate change exacerbated by the increasing scarcity of fossil fuels, renewable energies, in particular photovoltaic solar energy, offer a promising alternative. Solar energy is non-polluting, globally available and the
most widely distributed resource on Earth. However, the intermittency of this energy source considerably li(...)

Investigation of the Behavior of a Photovoltaic Cell under Concentration as a Function of the Temperature of the Base and a Variable External Magnetic Field in 3D Approximation
Boubacar Soro, Adama Ouedraogo, Mahamadi Savadogo, Ramatou Konate, Guyserge Tchouadep, Martial Zoungrana, Sié Kam
The photovoltaic (PV) cell performances are connected to the base photogenerated carriers charge. Some studies showed that the quantity of the photo-generated carriers charge increases with the increase of the solar illumination.
This situation explains the choice of concentration PV cell ( C = 50 suns ) in this study. However, the strong p(...)

Performance Analysis of a Radial N+/P Silicon Solar Cell in Steady State and Monochromatic Illumination
Aboubacar Savadogo, Bernard Zouma, Bruno Korgo, Ramatou Konaté, Sie Kam
In this paper, we investigate theoretically a radial n+/p silicon solar cell in steady state and monochromatic illumination. The purpose of this work is to analyze the effect of the cell base radius on its electrical parameters. The continuity equation in cylindrical coordinates is established and solved based on Bessel functions and boundarie(...)

Numerical Study of heat transfer in a differenally heated cavity
KONFE Amadou, SANEBAYE Adrien, BAYALA Alfred, KAM Sié
Laminar natural convection is studied in a square cavity filled with air whose
two vertical sides are subject to a temperature difference, while the other two
horizontal sides are adiabatic. The hot and cold wall temperatures are kept
constant. We have presented a dynamic and thermal study of pure natural
convection for different values of(...)

Diagnostic du fonctionnement de la Station d’Epuration de Kossodo : approche par la caractérisation des eaux usées brutes entrant
Mariam SAWADOGO*, Bila Gérard SEGDA, Paul Windinpsidi SAVADOGO, Antoine BERE
La Station d’Epuration (STEP) de Kossodo est confrontée à un problème de
fonctionnement entrainant le non-respect des normes de rejet recommandées
par le Burkina Faso et par l’OMS. Malgré cette situation, les eaux issues de
la station sont utilisées pour la production maraichère. De même, ces eaux
reversées dans la nature sont suscepti(...)
