    Al2O3-Cu hybrid nanofluid flow and heat transfer characteristics in the duct with various triangular rib configurations by Togun, Hussein, Homod, Raad Z., Sultan Aljibori, Hakim S., Abed, Azher M., Alias, Hajar, Hussein, Ahmed Kadhim, Biswal, Uddhaba, Al-Thamir, Mohaimen, Mahdi, Jasim M., Mohammed, Hayder I., Ahmadi, Goodarz

    Published 2024
    “…Key findings include: (1) the 60° rib configuration produced the highest local heat transfer coefficient, with the maximum occurring at the rib centers. (2) Increasing nanofluid concentration and Reynolds number enhanced heat transfer but reduced skin friction. (3) The optimal performance was achieved with 2 vol.% Al2O3–Cu at Re = 60,000. (4) Velocity contours revealed larger recirculation zones for 60° ribs compared to 45° and 90° configurations. (5) Turbulent kinetic energy was highest for 60° ribs, contributing to enhanced thermal performance. …”
