Molecular Dynamics Study of Aggregation in Nanofluid Flow: Effects of Liquid-Nanoparticle Interaction Strength and Particles Volume Fraction

摘要

Molecular dynamics simulations (MDSs) are carried on to examine the effects of liquid-nanoparticle (NP) interaction strength, size and number of nanoparticles on the aggregation process in liquid-based nanofluid flowing inside nanochannel. The results show that the increase in liquid-NP interaction strength leads to the reduction of aggregation rate. In addition, the increase in the size and number of NPs leads to more aggregation rate. Predicted results for aggregation trend are in good agreement with experimental data. Likewise, variations of velocity profile and density distribution of liquid particles inside nanochannel are explored.
