A study of a solar air collector with a mixed ‘‘porous” and ‘‘non-porous” composite absorber
A.O. Dissa, S. Ouoba, D. Bathiebo b, J. Koulidiati
In this work, a solar air collector with a composite absorber is designed and experimented. Its composite absorber results from the coupling of a non-porous absorber made of a corrugated iron sheet and a porous absorber made of a mesh of aluminum. The prototype collector was modeled in unsteady-state by considering heat capacity effects in its(...)

Broadband noise reduction by circular multi-cavity mufflers operating in multimodal propagation conditions
B. Ouédraogo, R. Maréchal, J.-M. Ville, E. Perrey-Debain
In this study, sound propagation through a circular duct with non-locally lining is investigated both numerically and experimentally. The liner concept is based on perforated screens backed by air cavities. Dimensions of the cavity are chosen to be of the order or bigger than the wavelength so acoustic waves within the liner can propagate para(...)

Correlation of Global Solar Radiation of Eight Synoptic Stations in Burkina Faso Based on Linear and Multiple Linear Regression Methods
Ousmane Coulibaly and Abdoulaye Ouedraogo
We utilize the multiple linear regression method to analyse meteorological data for eight cities in Burkina Faso. A correlation between the monthly mean daily global solar radiation on a horizontal surface and five meteorological and geographical parameters,which are the mean daily extraterrestrial solar radiation intensity, the average daily(...)

Synthesis, characterization and femtosecond nonlinear saturable absorption behavior of copper phthalocyanine nanocrystals doped-PMMA polymer thin films
S. Zongo, M.S. Dhlamini, P.H. Neethling, A. Yaod, M. Maaza, B. Sahraoui
In this work, we report the femtosecond nonlinear saturable absorption response of synthesized copper phthalocyanine nanocrystals (CPc-NCs)-doped PMMA polymer thin films. The samples were initially characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV–Vis and scanning electron microscopy (SEM) techniques. The crystal(...)

Modelling Study of Magnetic Field’s Effects on Solar Cell’s Transient Decay
Senghane Mbodji, Martial Zoungrana, Issa Zerbo, Biram Dieng, Gregoire Sissoko
Experimental setup of transient decay which occurs between two steady state operating points is recalled. The continuity equation is resolved using both the junction dynamic velocity (Sf) and back side recombination velocity (Sb). The transient excess minority carriers density appears as the sum of infinite terms. Influence of magnetic field o(...)

This work, based on the junction recombination velocity (Sfu) concept, is used to study the solar cell’s electric power at any real operating point. Using Sfu and the back side recombination velocity (Sbu) in a 3D modelling study, the continuity equation is resolved. We determined the photocurrent density, the photovoltage and the solar cell’s(...)
