The molecular properties like transmission of sound in nanofluids undergo changes in highly associated systems and dependent on the cohesive properties of liquids. In the present investigation an attempt is made to calculate the ultrasonic velocity and density of the prepared nanoparticles at different weight percentage with the base fluid Poly Vinyl Alcohol (PVA). Copper oxide (CuO) nanofluid was synthesized by transforming an unstable Cu(OH)2 precursor to CuO in PVA under an ultrasonication. The result shows that CuO-PVA nanofluid can be synthesized using this method. The obtained dried precursor was annealed at 300°C. The annealed sample and the dried precursor were sonicated with an aqueous solution of PVA having concentration 4wt%. For comparison, the synthesized nanoparticles are characterized by X-Ray powder Diffractometry (XRD), Fourier Transform InfraRed Spectroscopy (FTIR), Diffuse Reflectance Spectroscopy (DRS) and analyzed. After ultrasonication UV-Visible Spectroscopy (UV-Vis), Ultrasonic velocity, density and adiabatic compressibility were analyzed and the results were discussed. There is a good agreement between the data produced by ultrasonic spectroscopy and other measurements.

Abstract


The molecular properties like transmission of sound in nanofluids undergo changes in highly associated systems and dependent on the cohesive properties of liquids. In the present investigation an attempt is made to calculate the ultrasonic velocity and density of the prepared nanoparticles at different weight percentage with the base fluid Poly Vinyl Alcohol (PVA). Copper oxide (CuO) nanofluid was synthesized by transforming an unstable Cu(OH)2 precursor to CuO in PVA under an ultrasonication. The result shows that CuO-PVA nanofluid can be synthesized using this method. The obtained dried precursor was annealed at 300°C. The annealed sample and the dried precursor were sonicated with an aqueous solution of PVA having concentration 4wt%. For comparison, the synthesized nanoparticles are characterized by X-Ray powder Diffractometry (XRD), Fourier Transform InfraRed Spectroscopy (FTIR), Diffuse Reflectance Spectroscopy (DRS) and analyzed. After ultrasonication UV-Visible Spectroscopy (UV-Vis), Ultrasonic velocity, density and adiabatic compressibility were analyzed and the results were discussed. There is a good agreement between the data produced by ultrasonic spectroscopy and other measurements.
