Abstract
This study concentrates on investigating the implementation of a heat pipe system experimentally and theoretically by simulating a novel heat pipe model employing the MATLAB/Simulink® program, R2021a, using nanofluids obtained by adding 0.5 wt.% and 1 wt.% nickel ferrite, iron oxide, and ferric oxide magnetic nanoparticles to distilled water. A thermal-network dynamic representative was suggested to illustrate the thermal behavior of the heat pipe. The simulated system was capable to indicate the transient demeanour and steady-state temperature of the two-phase closed thermosyphon accurately. The experimental and simulated outcomes demonstrated that the best performance was accomplished using NiFe<sub>2</sub>O<sub>4</sub>/DW magnetic nanofluid with a proper deviation of ± 3.52%. Furthermore, the efficiency, thermal resistance, and Nusselt number of the system were boosted by approximately 22.24%, 9.3%, and 51.9% while utilizing NiFe<sub>2</sub>O<sub>4</sub> magnetic nanofluid corresponding to distilled water at 1 wt.%. A feedback control PID approach is assumed to perform a response within a fraction of a second as well as zero overshoot. The originality of the study is to experimentally and theoretically reveal the thermal behavior of NiFe<sub>2</sub>O<sub>4</sub> containing Ni and Fe and the thermal behavior of the only Fe-containing nanofluid compared to the nanofluids obtained with magnetic particles such as Fe<sub>2</sub>O<sub>3</sub> and Fe<sub>2</sub>O<sub>4</sub>
