dc.description.abstract	For the next generation of nanofluids, carbon nanomaterials are of tremendous interest. CnT and GnP, in particular, are extremely thermally conductive, and their usage in heat transfer nanofluids is a significant field of study. Using a concentric tube annular heat exchanger in the same operating circumstances, the heat transfer performance of GnP-nanofluid and MWCNT-nanofluid was investigated in this study. In the inner tube, the manufactured nanofluid flowed as a hot fluid in the reverse direction of a colder water flow in the annulus tube. The flow rate (1.5 L/min – 2.5 L/min) and concentration (0.01% – 0.35%) of nanofluid were varied in the experiment. At the same flow rates and nanofluid concentrations, the heat transfer coefficient of GnP-nanofluid was found to be greater than that of MWCNT-nanofluid. When an appropriate volumetric concentration is attained in both nanofluids, the favorable influence on heat transfer performance increase is at its peak. In comparison to MWCNT, our research reveals that GnP can increase heat transfer coefficient at lower volumetric concentrations and flow rates	en_US
