Bouwereou Bignan-Kagomna , Daniel Winde Nongue Koumbem , Abdoul Aziz Ouiminga , Bagaya Noufou , Ki Mibienpan and Issaka Ouedraogo
One of the most widely grown vegetable crops in Burkina Faso is onion and tomato. Solar drying is crucial for the conservation of these products. One of the most accessible solar dryers is the shell solar dryer, which allows these products to be dried hygienically. We were able to obtain some results from the experiment carried out over three(...)

Experimental Study of a Quadratic Boost: The Cascaded Connected Single Switch
Prince Abdoul Aziz Honadia; Bernard Zouma;Adama Ouédraogo;Fabé Idrissa Barro
The quadratic boost is studied under its real model. The equations, of the continuous conduction mode, descriptive of this model are established. From these equations, the expressions of the voltage gain and the efficiency are extracted. These two quantities are plotted as a function of the duty cycle in order to appreciate them in different o(...)

Physical and mechanical characterization of aggregates in Burkina Faso: implications for use as endogenous knowledge in civil engineering
Abdoul Aziz Ouiminga, Adélaïde Lareba Ouedraogo, Patrice Kouraogo, Mohamed Yerbanga, Sié Kam
Aggregates are the world's most widely exploited resource, surpassing even fossil fuels. They are mainly used for concrete production. On the one hand, due to restrictions on the use of river sand in some parts of the world to conserve river beds, demand for alternative fine aggregates in the construction sector has increased considerably. The(...)

THERMAL PERFORMANCE ASSESSMENT OF INCORPORATING A BIOMASS COMBUSTION CHAMBER AS A BACKUP SYSTEM IN BOX-TYPE SOLAR COOKERS
Iliyasse Konkobo, Jacques Nebie, Boubou Bagre, Armand Bowendkuni Korsaga, Tizane Daho and Antoine Bere (2024
Solar cookers are devices that allow cooking by using free solar energy. However, they cant operate during cloudy periods or at night. Theincorporating of biomass combustion chamber (hybrid cooker solar-biomass) is an alternative that uses an endogenous and renewable energy source for ecological and economical cooking. In this work, the perfor(...)

Assessment of Carbon Dioxide Emission Factors from Electricity Generation in Burkina Faso
Bernard Nana, Hamadi Zalle, Issoufou Ouarma, Tizane Daho, Arsène Yonli & Antoine Béré
Electricity generation is the second largest emitter of greenhouse gases, notably carbon dioxide (CO2), in the Burkinabe energy sector. Until now, Burkina Faso has used the default emission factors provided by the Intergovernmental Panel on Climate Change to assess its CO2 emissions from electricity generation, particularly in the context of t(...)

Investigating the Impact of Base Heating and External Electric Field on PV Cell Performance under Intense Illumination
Boubacar Soro, Guy Serge Tchouadep, Esso-Ehanam Tchedre Kpeli, Ousmane Souliga, Adama Ouedraogo, Issa Zerbo, Martial Zoungrana
The characterization of the performances of a PV cell is linked to intrinsic factors of this cell. It is therefore important for us to identify the favorable or unfavorable conditions that affect the performance of PV cells. It is from this
perspective that it seems judicious to us to study the simultaneous influence of the heating of the bas(...)

Performance Evaluation of Solar Chimney Draft: Application to Ventilation
Boukaré Ouedraogo, Adama Ouedraogo, Arouna Kabore, Kalifa Palm, Dieudonné Joseph Bahiebo
Ventilation is one of the factors contributing to energy consumption in buildings and food preservation. The solar chimney proves to be an alternative for reducing conventional energy consumption. Thus, in this study, the performance of a solar chimney with two active faces for thermally drawing air from a chamber for preserving agri-food prod(...)

Numerical Models and Methods of Atmospheric Parameters Originating in the Formation of the Earth’s Climatic Cycle
Wend Dolean Arsène Ilboudo1*, Kassoum Yamba1, Windé Nongué Daniel Koumbem2, Issaka Ouédraogo1
Atmospheric models are physical equations based on the ideal gas law. Applied to the atmosphere, this law yields equations for water, vapor (gas), ice, air, humidity, dryness, fire, and heat, thus defining the model of key atmospheric parameters. The distribution of these parameters across the entire planet Earth is the origin of the formation(...)
