The flow equation for a nanoscale fluid flow

• Proving the equation of the volume flow rate of a confined fluid through a nano channel.
• Substantiation of the flow equation for a nanoscale fluid flow by comparison with the molecular dynamics simulation results.
• New interpretation of the load-carrying mechanism of a physical adsorbed layer boundary lubrication.

The flow equation for a fluid confined in a nano channel proposed previously was re-examined by comparison with the molecular dynamics simulation (MDS) results. In themselves, this equation as well as the flow factor for the confined nano fluid flow were finely proven. The comparisons showed good agreements between the calculation results from this equation and the MDS results for both the Couette and Poiseuille flows.
