In present work, MgFe2O4-ethylene glycol nanofluids of various concentrations have been synthesized using ultrasonication method. The powdered MgFe2O4 nanoparticles are characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Particle size distribution of the nanoparticles in the base fluid has also been studied with the help of acoustical particle sizer (APS-100). Temperature dependent ultrasonic velocity, adiabatic compressibility and acoustic impedance at different concentration (0.1, 0.2, 0.5, 1.0 and 2.0 vol%) of MgFe2O4 have been investigated using ultrasonic interferometer. This paper is interested in systematic experimental study on the response of MgFe2O4-ethylene glycol nanofluids to the ultrasonic wave propagation. The main focus of the study is to understand the particle-fluid interaction and particle-particle interaction as function of concentration and temperature. The obtained results are discussed in correlation with the suitability of the present nanofluids for industrial application.
