Abstract
This is a study on the enhancement of the thermal performance of a thermosyphon heat pipe (THP) using the nanoparticle in a mixture of water and Triton X-100 (TX-100) surfactant. The effects of nanoparticle concentration, surfactant concentration, input power, inclination angle, and filling ratio on the thermal efficiency of THP is evaluated experimentally. Experiments were designed by the Taguchi method using Minitab software. According to the results, utilizing a nanofluid/surfactant mixture decreases the evaporator’s temperature, which decreases the thermal resistance and increases the thermal efficiency of THP. The maximum enhancement of thermal efficiency was observed to be 17.7%, and the maximum decrease in thermal resistance was 42.5% using the optimum concentration of nanofluid and TX-100 compared to water. The maximum thermal efficiency predicted by the Taguchi method was 0.8877, which was in good agreement with the experimental value of 0.917.
