摘要：
It has been demonstrated that there are nanobubbles on hydrophobic surface. Molecular dynamics simulation was adopted to investigate the impacts of the hydrophobic surface nanobubbles on fluid flow in nanochannel. A method for calculating the velocity of nanobubbles is presented. The results show that the bubbles on two plates enhance the velocity slip and disturb the flow. The behavior is attributed to the attractive force between nanobubbles.
