Dynamic Viscosity, Nanofluids, Nanoparticles, Modeling, Molecular Dynamics Simulations

There has not been a general experimental study that encompasses several categories of nanofluids or an empirical correlation that applies to all types or even several types of base fluids and nanoparticles. Since the viscosity of a suspension depends on the shape and distribution of the nanoparticles and aggregates, an accurate and general correlation for the viscosity of these heterogeneous mixtures may be difficult to derive. Therefore, there is need for more accurate and general correlations on the viscosity of Newtonian nanofluids based on the crucial input parameter such as the volume fraction, temperature and aspect ratio or some other geometrical or physical properties. In the present work a proper general functional form is proposed for the correlation of the effective viscosity of Newtonian nanofluids based on the experimental measurements as well as the available literature data. Moreover, Molecular Dynamics Simulation is considered to be carried out for some of the experimental systems in the proposed study.
