Nanofluids refer to fluids that contain suspended nanoparticles, typically with sizes less than 100 nanometers. These nanoparticles are often metallic or non-metallic and are dispersed in a base fluid, such as water, oil, or ethylene glycol. Nanofluids have gained attention in various industrial applications, including heating systems, due to their enhanced thermal properties compared to traditional fluids.

it's important to note that there are also challenges associated with the use of nanofluids, including issues related to stability, cost, and potential environmental and health concerns. Researchers and engineers continue to investigate and optimize nanofluid formulations for specific applications.

When considering the use of nanofluids in a heating system, it's essential to conduct thorough assessments, including performance testing, cost-benefit analysis, and consideration of any safety and regulatory implications.
