The effect of using water/CuO nanofluid and L-shaped porous ribs on the performance Evaluation Criterion of microchannels
Journal of Thermal Analysis and Calorimetry, 2019Co-Authors: Davood Toghraie, Farzad Pourfattah, Mohammad Mahmoudi, Omid Ali Akbari, Mousa HeydariAbstract:The main purpose of this study is numerically investigating the flow and heat transfer of nanofluid flow inside a microchannel with L-shaped porous ribs as well as studying the effect of porous media properties on the performance Evaluation Criterion (PEC) of the fluid. In the present paper, in addition to the pure water fluid, the effect of using water/CuO nanofluid on the PEC of microchannel was investigated. The flow was simulated in four Reynolds numbers and two different volume fractions of nanoparticles in laminar flow regime. The investigated parameters are the thermal conductivity and the porosity rate of porous medium. The results indicate that with the existence of porous ribs, the nanofluid does not have a significant effect on heat transfer increase. By using porous ribs in flow with Reynolds number of 1200, the heat transfer rate increases up to 42% and in flow with Reynolds number of 100, this rate increases by 25%.

a new supervised Evaluation Criterion for region based segmentation methods
Advanced Concepts for Intelligent Vision Systems, 2007Co-Authors: Adel Hafiane, Sebastien Chabrier, Christophe Rosenberger, Helene LaurentAbstract:We present in this article a new supervised Evaluation Criterion that enables the quantification of the quality of region segmentation algorithms. This Criterion is compared with seven well-known criteria available in this context. To that end, we test the different methods on natural images by using a subjective Evaluation involving different experts from the French community in image processing. Experimental results show the benefit of this new Criterion.
