Abstract

The present paper reports the comparison of free length thermodynamically and acoustically of alpha alumina (α-Al2O3) nano suspension in ethanol base fluid. α-Al2O3 nanoparticles were synthesized through alkoxide route using sol-gel method. Intermolecular free length has been calculated by thermo acoustical method at different temperatures over the entire range of concentrations and compared with the valued obtained from well established thermodynamic method. The ultrasonic velocity measurement at 4 MHz with an interferometric technique has been made on alpha alumina (α-Al2O3) nano suspension in ethanol base fluid. Measurement was taken for the density. The intermolecular free length was calculated from the velocity and density measurements. Free length is related with the surface of nanoparticles and nanoparticle surfactant interactions and help for the study of thermo acoustic and thermodynamic properties of nanosuspension.
