Boehmite nanofluids were synthesized by two step method. In this method Boehmite nano-powder was initially prepared and the powder was dispersed in methanol base fluid by magnetic stirrer method. The prepared nanopowder was characterized by X- ray diffraction (XRD), FTIR and Scanning electron microscopy (SEM). Average particle size has been estimated by using Debye-Scherrer formula. It was found to be about 50 nm. Nanofluids of Boehmite in methanol base fluid were prepared for various molar concentrations and their acoustical studies were made such that different types of interactions could be assessed. Thermo-acoustical parameters of this nanofluids system were computed from ultrasonic velocities, densities and viscosities at temperatures 293K, 298K, 303K, 308K and 313K at fixed frequency 5 MHz over the entire range of concentrations. The obtained results of present investigation have been discussed in the light of interactions between the Boehmite nanoparticles and the molecules of methanol based fluids.

The prepared nanopowder was characterized by X- ray diffraction (XRD), FTIR and Scanning electron microscopy (SEM). Average particle size has been estimated by using Debye-Scherrer formula. It was found to be about 50 nm. Nanofluids of Boehmite in methanol base fluid were prepared for various molar concentrations and their acoustical studies were made such that different types of interactions could be assessed. Thermo-acoustical parameters of this nanofluids system were computed from ultrasonic velocities, densities and viscosities at temperatures 293K, 298K, 303K, 308K and 313K at fixed frequency 5 MHz over the entire range of concentrations.
