“…Nanofluids have become an active research area due to their unique thermal and physical properties. Nanoparticles added to fluids can significantly enhance the heat transfer properties of the resulting nanofluid compared to conventional fluids [4]. The increased heat transfer efficiency is attributed to the high surface area of nanoparticles, which allows for better interaction with the fluid molecules, resulting in improved thermal conductivity.…”

This study examines the effects of particle size and heat pipe angle on the thermal effectiveness of a cylindrical screen mesh heat pipe using silver nanoparticles (Ag) as the test substance. The experiment investigates three different particle sizes (30 nm, 50 nm, and 80 nm) and four different heat pipe angles (0°, 45°, 60°, and 90°) on the heat transmission characteristics of the heat pipe. The results show that the thermal conductivity of the heat pipe increased with an increase in heat pipe angle for all particle sizes, with the highest thermal conductivity attained at a 90° heat pipe angle. Furthermore, the thermal resistance of the heat pipe decreased as the particle size decreased for all heat pipe angles. The thermal conductivity measurements of the particle sizes—30, 50, and 80 nm—were 250 W/mK, 200 W/mK, and 150 W/mK, respectively. The heat transfer coefficient values for particle sizes 30 nm, 50 nm, and 80 nm were 5500 W/m2K, 4500 W/m2K, and 3500 W/m2K, respectively. The heat transfer coefficient increased with increased heat pipe angle for all particle sizes, with the highest heat transfer coefficient obtained at a 90° heat pipe angle. The addition of Ag nanoparticles at a volume concentration of 1% reduced the thermal resistance of the heat pipe, resulting in improved heat transfer performance. At a heat load of 150 W, the thermal resistance decreased from 0.016 °C/W without nanoparticles to 0.012 °C/W with 30 nm nanoparticles, 0.013 °C/W with 50 nm nanoparticles, and 0.014 °C/W with 80 nm nanoparticles. This study also found that the heat transfer coefficient increased with increased heat pipe angle for all particle sizes, with the highest heat transfer coefficient obtained at a 90° heat pipe angle.

Adding additive with nano‐sized and considering porous media, new container has been generated and numerical technique was employed to model the convection process of cooling the four lobed surfaces which is situated inside three lobed tanks. Uniform flux was considered for four lobed surfaces while the outer surface is cold wall. With neglecting advection term due to employ of Darcy law, simpler form of momentum equations was appeared with is coupled with source term of magnetic field. Moreover, mixture model for testing fluid was applied with incorporating the efficacy of shape of nanopowders. Dispersing nanoparticles causes augmentation in Nu around 41.33% because of augmenting conductivity. The elevation of Ra makes Nu to increase around 38.98% in absence of Ha while this augmentation reaches to 1.54% in existence of Ha which means that domination of conduction in appearance of MHD. Augmenting shape parameter leads to rise of Nu around 11.72% while increment of Ha causes this function to reduce around 11.73%.
