Nanofluid is a solid-liquid composite material consisting of solid nanoparticles with size typically of 1-100 nm suspended in liquid. Nanofluids have attracted great interest recently because of reports of greatly enhanced thermal properties. Nanoparticle of metals, metal oxide and semiconductor exhibited significantly distinct physical, chemical, optical, magnetic and biological properties from their matter because of their high surface to volume ratio. When a small amount of nanoparticles dispersed in host fluids, can provide dramatic improvements in the thermal properties of the fluids. More recently there has been an increasing interest in the acoustical properties of suspensions for acoustic telemetry through drilling fluids as well as a rising demand for ultrasonic particle size instrumentation. Characterization of nanoparticle is important to understand and to control nanoparticle synthesis for various applications. The thermodynamic properties provides useful information regarding physical and chemical behavior of pure fluid as well as its suspension. The thermodynamic study of nanoparticles suspension provides the information regarding the interaction at the atomic level in the suspension. Weak interactions between the components of the nanofluids can be determined only by nonconstructive techniques. Surface area of the nanomaterial is increased with reduced in their size. At the nanoscale dimensions, the material properties changes significantly from their bulk matter. When matter is reduced in size, it changes its characteristics, caused by the change of mechanical, electronic, physical, chemical, optical, magnetic and biological properties.
