Numerical investigation explores thermal behavior in ribbed microchannels using nanofluid, suggesting improved performance.
A numerical investigation in tow dimensions was carried out to exanimate the thermal and the hydrodynamic characteristics of nanofluid within ribbed microchannel. The nanofluid, composed of alumina (Al 2 O 3 ) nanoparticles dispersed in water, was analyzed at different volume fraction 0%, 2% and 4%. The continuity, momentum and the energy equation were resolved based on finite volume method. The main studied parameters were the Reynolds number, nanoparticles concentration and rib size. The findings indicated that increasing both of nanoparticles volume fraction and Reynolds number led to improve Nusselt number and the Poiseuille number. Additionally, the existence of ribs contributed to enhance the thermal performance of microchannel.
