Guy Christian Tubreoumya, Téré Dabilgou, Eloi Salmwendé Tiendrebeogo, Jacques Nebié, Boubou Bagré, Belkacem Zeghmati, Alfa Oumar Dissa, Jean Koulidiati, Antoine Bere
This paper presents an optimization study of an adsorption solar refrigerator through dynamic modeling and simulation of the system behavior using the zeolite/water couple. Thus, a mathematical model representing the evolution of heat and mass transfer at each component of the adsorption solar refrigerator has been developed. The results of t(...)

Comparative study of thermophysical parameters of different types of upholstery wood and the influence of density on combustion parameters at microscale
Abdoul Fayçal BAGUIAN, Salifou Koucka OUIMINGA, Sampawinde Augustin ZONGO, Ibrahim Harouna GADO, Rodolphe SONNIER
The fire behaviour of five types of wood was studied on a microscale. Some thermophysical parameters such as thermal conductivity, effusivity and diffu- sivity were also evaluated. The microscale analysis is based on the analysis of several parameters such as the assessment of heat released rates (HRR), peak heat released rates (pHRR), total h(...)

Thermal Performance Assessment of a Box-type Solar Cooker with an Inclined Collecting Surface and Kapok Wool Insulation
Jacques Nébié , Sidiki Zongo , Augustin. Zongo , Guy. Tubreoumya , Zacharie S. Kam , Serge W. Igo , Tizane Daho , Ilyassé Konkobo , Antoine Béré and Belkacem Zeghmati
The present work reports the thermal performance of a box-type solar cooker insulated with kapok
wool, a local plant with a low thermal conductivity. The experimental results obtained indicate that
the absorber plate reached a maximum temperature of 155.2 °C. Moreover, the maximum power of
the cooker was 87.5 W with an efficiency of 35.45 %(...)

Effects of Temperature, Pressure and PhysicoChemical Characteristics on the Atomization and Disintegration of Jatropha Oil and its Formulations
Dabilgou Téré , Zongo S. Augustin , Bagre Boubou , Tubreoumya Guy Christian , Sandwidi Sayouba , Haro Kayaba , Daho Tizane , Koulidiati Jean , Sanogo Oumar , Zeghmati Belkacem and Bere Antoine
The physicochemical characteristics of vegetable oils, the atomization and the particle size of the
spray are fundamental aspects for the simulation of their combustion on burners.
In this study, the influence of temperature and pressure on the disintegration of the jet of jatropha oil
and its mixture with gas oil was simulated on a Riell(...)

LIGHT CONCENTRATION SOLAR CELL: TEMPERATURE PROPER AND DYNAMIC EFFECTS ON ELECTRICAL PARAMETERS DETERMINED BY USING J-V AND P-V CHARACTERISTICS
MAHAMADI SAVADOGO, AMADOU KONFE, IDRISSA SOURABIE, BOUBACAR SORO, RAMATOU KONATE, MARTIAL ZOUNGRANA, ISSA ZERBO, DIEUDONNÉ JOSEPH BATHIEBO
The solar cell is assumed to be under light concentration (C=50 Suns) which leads us to take into consideration the
electric field induced by electrons concentration gradient. We also take into consideration temperature influence on
electron and hole diffusion parameters, on carrier generation rate, on carrier intrinsic concentration and on(...)

Energy Performance Analysis of B1-3.5mm Burner Model of Fasobio-15 Biodigester Biogas Cookstoves
Noufou Bagaya1*, Issaka Ouedraogo2, Daniel Windé Nongué Koumbem1, Gwladys Wendwaoga Sandwidi3 and Florent Pelega Kieno1
In Burkina Faso, finding wood for cooking is still a headache for rural households due to the advancing desert. Here, we try to bring a new way for farmers who already have a biodigester and convince those who are reluctant to adopt this work to reduce their dependence on wood. For this purpose, a characterization of the energy performance of(...)
