| Abstract | The synthesis of the Beryllium oxide (BeO) nanoparticles was prepared via chemical precipitation. BeO nanoparticles were characterized by annealing them at 840?C. Its hexagonal shape was perfect. These results were confirmed using fourier transform infrared (FTIR) as well as Raman spectra. Raman as well as FTIR spectra demonstrate the Be-O-Be stretching connection between the beryllium and oxygen atoms. To make BeO nanofluids, the synthesized BeO nanoparticles were sonicated with a silicone oil base fluid. The silicone oil base fluid was infused with BeO using sonication at concentrations of 0.0005%, 0.001%, 0.0015%, 0.002%, 0.0025%, as well as 0.003% by volume. Ultrasonic velocity, viscosity and density were measured for the prepared silocone oil based BeO nanofluids. Silicone oil based BeO Nanofluids have a higher velocity value because of particle-fluid molecule interactions. The relationship between the concentration (?) (0.0005, 0.001, 0.0015, 0.002, 0.0025, 0.003 vol. %) as well as temperature of nanofluids was also studied (313 Boltzmann's constant (K), 323 K as well as 333 K) using Kininogen Domain (KD2) thermal analyser. Silicone oil-based BeO nanofluid has a thermal conductivity increase of up to 30%, comparatively to the base fluid. As the temperature rises, particle and fluid's acoustic properties change almost linearly, suggesting weaker intermolecular interactions. |
