Microstructure of the Poiseuille flow in a model nanofluid by molecular dynamics simulation

The microscopic behavior of nanofluids in the Poiseuille flow in a nanochannel is examined by means of molecular dynamics simulation through visual observations and statistic analysis. For nanofluid flows inside the nanochannel, a clustering effect is observed during the time evolution of the system. The cluster moves along the centerline of the nanochannel due to the maximum velocity in the middle part of the Poiseuille flow. The attractive force is believed to be the primary culprit behind the agglomeration of nanoparticles.
