A nanoparticle suspension is considered as a three-phase system including the solid phase nanoparticles the liquid phase fluid media and the interfacial phase which contributes significantly to the system properties because of its extremely high surface-to-volume ratio in nanofluids. The systems engineering approach was applied to nanofluid design resulting in a detailed assessment of various parameters in the multivariable nanofluid systems. The relative importance of nanofluid parameters for heat transfer evaluated in this article allows engineering nanofluids with desired set of properties. Introduction Suspensions of solid submicron- and nanometer-sized particles in various fluids also called nanofluids have been considered for applications as advanced heat transfer fluids for almost two decades. However due to the wide variety and the complexity of the nanofluid systems no agreement has been achieved on the magnitude of potential benefits of using nanofluids for heat transfer applications. Large volume of studies devoted to characterization of individual thermo-physical properties of nanofluids such as thermal conductivity viscosity and agglomeration of nanoparticles has been summarized in a number of review articles 1-9 . Evaluation of cooling efficiency . ability to remove heat from the heat source includes assessing flow regime-dependent contributions from thermal conductivity viscosity specific heat and density of .
