Nanofluids colloidal suspensions of nanoparticles in base fluids have attracted increasing research interest due to their improved heat transfer characteristics. This study investigates the use of silver nanofluids as a medium to enhance heat transfer in a shell-and-tube heat exchanger. Silver nanoparticles, known for their high thermal conductivity and stability, were dispersed in a base fluid (water/ethylene glycol) at different concentrations. Experimental tests were conducted by circulating nanofluids through the tube side, while hot fluid passed through the shell side. Results demonstrate a significant increase in heat transfer rate compared to the base fluid alone, attributed to the superior thermal conductivity of silver nanoparticles. Effects of concentration, flow rate, and temperature differential were analyzed. Challenges such as nanoparticle stability and aggregation were also discussed, along with potential mitigation strategies.
