 This study investigated the behavior of hybrid nanofluids consisting of copper particles and alumina particles suspended in water. The hybrid nanofluids were tested in a porous cavity with the goal of improving the thermal distribution of traditional fluids. The authors developed a mathematical model based on the Boussinesq-Darcy force and the Kuhkleinsterle model to analyze the behavior of the hybrid nanofluids. They found that the hybrid nanofluids improved the thermal distribution of traditional fluids by increasing the velocity of the fluid and reducing the temperature gradient. Additionally, they determined that the hybrid nanofluids had a higher heat transfer rate than traditional fluids due to their increased viscosity and surface area.
