Experimental Study of the Airflow in Natural Convection in an Innovative Prototype of Solar Chimney PowerPlant, under Climatic Conditions in Ouagadougou, Burkina Faso
Salifou Ouédraogo, Moctar Ousmane, Ladifata Mogmenga, Thierry Sikoudouin Maurice Ky, Sié Kam, Joseph Bathiébo
Objectives: In sunny regions, chimney solar power plants are a promising technology because they depend mainly on solar energy. However, chimney solar power plants require an optimal design of the power plant components to improve its reliability and scalability. As the collector is one of the essential components of the solar chimney power pl(...)

Modelling the Influence of Low Energy Electrons Emitted from Pm-147 on the Performance of a Silicon PV Cell
G. S. Tchouadep, E. K. Tchédré, I. Sourabié, I. Zerbo, and Martial Zoungrana
This paper investigated, using 1-D analysis, the effect of low energy electrons emitted from Promethium – 147 (Pm-147) on the performance of a silicon PV cell. The Pm-147 source is chosen due to the penetration depth of beta particles with the average kinetic energy of 62.5 KeV emitted from Pm-147, because at this depth the are able to generat(...)

Impact of the Thicknesses of the p and p+ Regions on the Electrical Parameters of a Bifacial PV Cell
Ramatou Konate, Bernard Zouma, Adama Ouedraogo, Bruno Korgo
The present paper is about a contribution to the bifacial PV cell performances improvement. The PV cell efficiency is weak compared to the strong energy demand. In this study, the base thickness impacts and the p+ zone size infl u-ence are evaluated on the rear face of the polycrystalline back surface field bi-facial silicon PV cell. The p(...)

Performance Assessment of a Box Type Solar Cooker Using Jatropha Oil as a Heat Storage Material
Jacques Nébié, Sidiki Zongo, Guy C. Tubreoumya, Augustin S. Zongo, Ilyassé Konkobo, Boubou Bagré, Ali Diané, Tizane Daho, Serges W. Igo, Belkacem Zeghmati, Antoine Béré
Solar cookers are a good option in developing countries with high solar potential for environmentally friendly cooking and reduced pressure on forests. However, they are still affected by the intermittency of the sun. In order to overcome this problem, in this work, a box type solar cooker integrated Jatropha oil as a heat storage material is(...)

Salmwende Eloi Tiendrebeogo1, 2, *, Tubreoumya Guy Christian1 , Kafando Guetinsom Jean1 , Nana Bernard1, 2, Kere Moumini2 , Dissa Alfa Oumar1 , Koulidiati Jean1 , Bere Antoine1
In order to find heat production techniques for drying and heating applications of premises in tropical climates from
process characterization studies, a flat air collector with air and forced convection was first designed. A simulation of solar
radiation, thermal behavior of the solar collector and an experimental test of the latter were(...)

SIMULATION OF THE OKRA DRYING PROCESS IN A SOLAR TOWER DRYER
Germain Wende Pouire Ouedraogo , Boureima Kabore , Nebon Bado , Vincent Zoma , Sie Kam and Dieudonne Joseph Bathiebo
This work presents the simulation of the drying air flow in a solar tower dryer as well as the okra drying process with FORTRAN software. The explicit Euler method was used for solving the heat transfer and mass transfer equations. The heat transfer equations reflect the flow of hot air from the manifold and directed into the drying chamber, w(...)

Measurements of natural radioactivity and exposure rates in soil samples from Ouagadougou, Burkina Faso
Z. Yaméogo, D. Nabayaogo, O. Kaboré, C. Bangou , I. Zerbo, M. Zoungrana
Natural radioactivity could be found in various degrees in all media in the environment (water, soils, vegetation, food), and depending on the activity and concentration of radionuclides dealt with, the principal concern is the consequence of exposure to low doses and low dose rates. In this work, we present a study on the measurements of natu(...)
