Investigation of Screen Mesh Wick Heat Conduit using Aluminum Oxide Nanofluid with Deionized Water as the Base Working Fluid
J. Environ. Nanotechnol., Volume 13, No 4 (2024) pp. 406-416
Abstract
This investigation was focused on analyzing heat conduits' heat energy transport characteristics using deionized water and aluminum oxide nanofluid as the working media. By varying the angle of inclination of the heat conduit from 0 to 90° and adjusting the heat load from 40 to 200W, comparisons were made between deionized water (base fluid) and water-soluble Al2O3 nanofluid. Performance evaluation parameters included thermal efficiency, heat resistance, and heat transfer coefficient. Compared to the base fluid, the use of the nanofluid improved the thermal performance of the screen mesh wick heat conduit, as evidenced by the experimental findings. The heat transfer coefficient increased from 5.68 to 21.7% due to the enhanced heat load and changed orientation due to gravitational effects. Furthermore, the overall thermal resistance decreased from 6.85 to 17.7% with the rise in heat load and orientation. Incorporating nanoparticles and altering the orientation not only expanded the operational range but also enhanced the overall thermal efficiency of the heat conduit when compared to the base fluid.
