In this study, we numerically investigated the influence of the baffle length and emissivity of the walls on heat transfer in a mixed convection coupled with radiation in a rectangular cavity ventilated. The baffle length is used Lb = 0.3, 0.5 and…

Dans cet article, l’influence du nombre et la hauteur des ailettes d’un dissipateur de chaleur sur le transfert thermique par convection mixte dans une cavité renfermant des composants électroniques a été simulé numériquement. Le nombre d’ailettes…

Dans cette étude, nous avons simulé numériquement l’influence de la vitesse de rotation  du positionnement des chicanes et des cisaillements des parois sur le transfert de chaleur par convection mixte dans une cavité carrée. La paroi verticale gauche…
