Abstract

This study is about the performance evaluation of a shell and tube heat exchanger operated with nanofluid. Thermal conductivity, viscosity, and density of the nanofluids were increased, but the specific heat of the nanofluids was decreased with increasing the concentrations of the particles. The convective heat transfer coefficient was found to be 2–15 % higher than that of water at 50 kg/min of both side fluid. Nevertheless, energy effectiveness has improved about 23–52 % for the above-mentioned nanofluids. As, energy effectiveness (ɛ) is strongly depends on the density and specific heat of the operating fluids therefore, maximum ɛ has obtained for ZnO–W nanofluid and lowest found for SiO₂–W nanofluid.
