Évaluation des pertes d’eau par évaporation et impact du changement climatique sur les retenus d’eau :
BAYALA Alfred , KONFE Amadou, CHESNEAU Xavier,ZEGHMATI Belkacem ,KIENO P. Florent, BATHIEBO Joseph
Une étude numérique des transferts de chaleur et de masse dans une retenue d’eau de
grande dimension est présentée. Cette retenue d'eau est assimilée à un réservoir
parallélépipédique dont les parois verticales et inférieures sont adiabatiques et imperméables.
Les équations qui régissent la convection naturelle dans l'eau sont résolues par(...)

Study of the Impact of the Magnetic Field on the Electrical Parameters of the Radial Junction Photovoltaic Cell under Monochromatic Illumination
Cyrile Constant Moyenga, Bernard Zouma, Ramatou Konate, Aboubacar Savadogo, Bruno Korgoa and Sié Kam
The present work is a theoretical study of the radial junction photovoltaic cell subjected to a magnetic field under monochromatic illumination. From a three-dimensional description, new analytical expressions of photocurrent density, photovoltage and electric power as a function of the magnetic field are established and by simulation on the M(...)

Thermal and Dynamic Study of Convection-Radiation Coupling in a Closed Enclosure
Sanembaye Adrien, Konfé Amadou, Toussakoe Karim, KY Thierry Sikoudouin Maurice and Bathiebo Dieudonné Joseph
In this work, we present a two-dimensional study of natural convection in a square air-filled cavity whose two vertical sides are subjected to a temperature difference, while the other two horizontal ones are adiabatic. The numerical method used is that of finite elements used in the COMSOL calculation code. We first studied pure natural conve(...)

An advanced LIGO and Virgo’s third observing run brought another binary neutron star merger (BNS) and the first
neutron-star black hole mergers. While no confirmed kilonovae were identified in conjunction with any of these
events, continued improvements of analyses surrounding GW170817 allow us to project constraints on the Hubble

Assessing the Efficiency of the Zagtouli Solar Plant: A Large-Scale Grid-Connected PV System in Burkina Faso
Abdoulaye Kaboré, Samuel Ouoba, Kayaba Haro, Tongonmanegde Leonard Ouedraogo, Boubou Bagré, Bowendkuni Armand Korsaga, Antoine Béré
This paper presents an evaluation and analysis of the energy performance of a 33.7 MWp solar photovoltaic plant. Monitoring data for 36 months (January 2019-December 2021) have been used to evaluate the performance of the power plant according to the IEC 61724 standard. Normalized parameters that are (i) performance ratio, (ii) reference yield(...)

Assessment of carbon dioxide emission factors from power generation in Burkina Faso
Bernard Nana, Hamadi Zalle, Issoufou Ouarma, Tizane Daho , Arsène Yonli, Antoine Bere
Power generation is the second largest source of greenhouse gases (GHGs), particularly carbon dioxide (CO2), in Burkina Faso's energy sector. When preparing the National Communications on Climate Change, Burkina Faso uses the default emission factors of the Intergovernmental Panel on Climate Change (IPCC) to estimate emissions from power gener(...)

Establishment of a model for the calculation of the COP of a solar adsorption refrigerator
KONFE Amadou, NANA G Gilbert, OUEDRAOGO Salif, KAM Sié
This paper deals with the evaluation of the Coefficient of Performance (COP)
of solar adsorption refrigeration. In the literature, simulation models to predict
the thermal behaviour and the coefficient of performance of these systems
are uncommon. This is why we suggest a model to simulate the operation
of the machine in a typical hot and(...)

Perte de masse des étoiles évoluées via des observations avec SPHERE au VLT Perte de masse des étoiles évoluées via des observations avec SPHERE au VLT
N. Aymard. Badolo, S. Zacharie Kam, Eric Lagadec, Vincent Hocde, Fabrice Bado, Jean Koulidiati
Les étoiles branche asymptotique des géantes (AGB) perdent une énorme quantité de matière d’une manière peu comprise à ce jour. Nous avons voulu mieux comprendre les mécanismes auteurs de la diminution considérable de la masse des étoiles pouvant avoisiner les trois quarts de la masse initiale de l’étoile. Nous avons étudié les spectres IRAS(...)

Assessment of the thermal efficiency of a concentrated photovoltaic/thermal (CPV/T) hybrid system with water as heat transfer fluid,
KONFE Amadou, KORGHO Bruno, Nana G. Gilbert, BAGBILA Eloi, AMADOU Oumarou Fati, KAM Sié
Interest in solar energy is growing by the day, because it is clean and unlimited. Concentrated
photovoltaic-thermal (CPV/T) systems are one of the systems that are attracting a great deal of
attention among solar energy systems. In this work, a study of a hybrid concentrated photovoltaicthermal
(CPV/T) system that enables the simultaneous(...)

Thermal Study and Modeling of the Cold Room of a Solar Adsoption Refrigerator
Amadou Konfe, Mahamadi Savadogo, Loukman Ouedraogo, Ousmane Moctar, Sié Kam
In this work, we are interested in the study of the thermal exchanges which
take place at the evaporator of an adsorption refrigerator. Due to the cost of
designing experimental devices and the impossibility of studying the influence
of certain parameters experimentally, an alternative would be simulation.
The aim is to provide a model for(...)

This work focused on the impacts of the base doping rate (Nb) and the emitter doping rate (Ne) on the internal
quantum efficiency (IQE) of a bifacial polycrystalline silicon solar cell, under static conditions and monochromatic
illumination. IQE is defined as the ratio of the number of electron-hole pairs or charge carriers generated to the(...)

Feasibility of Efficient Pyrolysis of Wood Chips and its Product Yield in Developing Countries
Jean Fidele Nzihou a*, Pierre Girod b , Salou Hamidou c , Yann Rogaume b , Bila Gerard Segda d and Frederic Ouattara a
This paper is about the feasibility of combustibles gases like methane, ethane and carbon monoxide
production from wood pyrolysis. This first laboratory experimental stage objective was to see what
products can be obtained from wood pyrolysis in absence of oxygen and presence of nitrogen. The
effect of temperature on the product yields w(...)
