Entropy Analysis of Nano fluid in Open Cell Copper Metal Foam

Abstract

Abstract: Entropy analysis plays a crucial role in understanding the thermodynamic behavior and energy conversion processes in various thermal systems. Previous studies have explored various techniques, such as local and global entropy generation analysis and exergy analysis, to quantify entropy generation and identify optimization strategies. The research findings highlight the significance of entropy analysis in optimizing the performance of porous media-based systems in the presence of Nano fluids which enhance heat transfer. The study's findings show how entropy analysis might improve heat transfer by improving the functionality of systems based on porous media. With different pore densities (PPI = 10, 20, and 40), nanoparticle mass fractions (from 0.0 to 0.5 wt%), and Reynolds numbers (Re = 414-1119), the impact of metal foam on entropy formation was investigated. The total amount of nanofluids first decreases, then increases with an increase in mass fraction, and finally decreases with an increase in PPI. The least amount of total entropy is produced by nanofluids with = 0.3 wt% under PPI = 40. It demonstrates that in this ideal scenario, the irreversible loss between the route and the working fluid may be reduced, actively reducing the system's entropy generation
