Modeling the Influence of Raleigh Numbers on Thermal and Fluidic Behaviors in a Trapezoid-shaped Cell
Windé Nongué Daniel Koumbem, Bouwèreou Bignan-Kagomna , Noufou Bagaya , Wend Dolean Arsène Ilboudo, Pare Daouda, Issaka Ouédraogo, Sié Kam
We model the influence of Raleigh numbers in a trapezoidal cavity. One wall among the sloping walls is exposed to a heat flux density Q=100 W/ m2 and the other inclined wall is kept adiabatic. The temperature of the two horizontal walls is assumed to be constant such that Tsup=305K is greater than Tinf=300K. The equations of heat and mass tran(...)

Experimental study of improved cookstove with primary and secondary sources
DIANDA Boureima, OUEDRAOGO Lareba Adélaïde, COMPAORE Abdoulaye, ZONGO Wendtoin Estelle, KAM Sié and Dieudonné Joseph Bathiébo
Improved cookcookstoves are cooking devices using biomass such as wood and charcoal. Although existing improved cookcookstoves contribute to reducing wood consumption, this consumption is still considerable, and the smoke produced is a source of many illnesses. It is therefore necessary to work on further improving these "improved cookstoves".(...)
