Acoustical and thermal conductivity studies on CuO/DEA-benzene hybrid nanofluids

Binary organic liquid based copper oxide nanofluids of various concentrations have been prepared through ultrasonically assisted chemical solution method. Ultrasonic studies, refractive indices, densities are carried out for the nanofluids for various temperature where Thermal conductivity was also measured for the nanofluids at room temperature. The molecular interactions responsible for the changes in acoustical parameters with respect to concentration and temperature are discussed.
