摘要：

In this study, the effect of Fe3O4 magnetic nanoparticles on the efficiency of helically coiled tube heat exchanger (HCHE) has been investigated both numerically and experimentally. The solution of 20 % Ethylene glycol (EG) and distilled water is used as the base fluid. The effect of parameters including volume fraction of nanoparticles, coil inlet temperature, flow rate at the shell/coil side, and coil diameter on the heat transfer of the heat exchanger has been investigated. The results show that with increasing the flow rate on the coil side, the heat transfer coefficients and the Nusselt number are increased. It was observed that the heat transfer coefficient for the solution of distilled water-ethylene glycol increases by about 60 % with 0.1 volume fraction of Fe3O4 nanoparticles. As the coil inlet temperature increases from 40 degrees C to 60 degrees C, the overall Nusselt number increases by 22 %. As expected, as the nanofluid flow rate increases, the heat transfer coefficient increases. For a wide range of flow rates, the internal and external heat transfer coefficients of the coil have been obtained.
