摘要：

Spreading of nanofluids on solid substrate was studied via molecular dynamics simulations.Simulation models for two immiscible fluids(oil and water based nanofluids)confined in a slit between two planar solid walls were set up.The influence of the volume concentration of the nanoparticles on the three-phase contact line motion was investigated.We found that the larger volume concentration results in more visible nanoparticle adsorption on solid surface.This efect further induces an advancing displacement of the contact line compared with the meniscus profiles in low concentration case and that with the absence of nanoparticles.These findings are consistent with the previous experimental and theoretical results and provide the atomic-scale understanding on nanofluid spreading.
