dc.description.abstractRed mud consists of valuable metal oxides as part of its chemical composition. This research investigates the use of water-based red mud nanofluids in circular copper tube under turbulent flow conditions for heat transfer applications. The focus is on entropy and exergy analysis, with an inlet fluid temperature of 60 �C. The study explores the thermophysical properties and stability of the nanofluid at concentrations ranging from 0 to 0.75 vol%. The findings reveal that both the heat transfer coefficient and pressure drop of the red mud nanofluids improve with concentration and Reynolds number. The maximum observed enhancement in Nusselt number is 28 % for the 0.75 vol% compared to water. Interestingly, the minimum total entropy generation of 0.13 and the maximum exergy of 1.8 are also observed for the 0.75 vol% nanofluid. While the friction factor of the red mud nanofluids increases with concentration, it decreases at a higher Reynolds number. The maximum Performance Index (PI) of 1.61 is achieved for the 0.75 vol% concentration. ? 2024en_US
