A bstract : This paper deals with experimental modeling of the unsteady junction flow features in the vicinity of an isoflux heated wall with mounted insulated rectangular ribs representing three distinctive ribbed test geometries. Both flow visualizations and surface temperature distributions show that the blockage effect upstream of the ribs, as well as the presence of complex eddy structures inside the open cavities, significantly affect the heat transfer process. All the configurations indicate degraded heat transfer performance in the area close to the ribs and an enhancement just downstream from the last rib.
