Author(s) : SINGH S. K., SUKLEE J.

Summary

This study conducts a numerical analysis to compare the performance of an active magnetic regenerative system (AMR) using Al₂O₃ nanofluids, multi-walled carbon nanotube (MWCNT) nanofluids, and hybrid nanofluids composed of Al₂O₃(50%) and MWCNT (50%), with volume concentrations ranging from 0-1%. The evaluation focuses on thermophysical propertiesand overall system performance. The results indicate that MWCNT nanofluids, particularly at higher concentrations, outperform other nanofluids, demonstrating superior thermal conductivity and heat transfer rates. MWCNT nanofluids also achieve lower cold-end temperatures and a greater temperature span between the hot and cold ends of the AMR. However, the higher viscosity of MWCNT nanofluids poses challenges by increasing the pumping power required. These findings highlight the significant potential of MWCNT nanofluids to enhance the efficiency of magnetic regenerative systems, suggesting promising advancements for advanced thermal management and sustainable energy applications.
