Molecular Scale Flow Structure Near a Solid Surface : Analysis of a Lennard-Jones Fluid in a Narrow Channel

The non-equilibrium flow near a solid surface is simulated using the molecular dynamics method. The fluid is set to be a Lennard-Jones fluid where the interacting potential between the fluid molecules is the Lennard-Jones potential. The fluid molecule is given the parameters of Xe and the solid molecule is that of Pt. First, the system is maintained at thermal equilibrium and the density distribution, radial distribution, surface coverage, pressure distribution, interface tension, and adsorption coefficient of the fluid molecule is analyzed. Next, shear velocity was given to the solid molecules to drive the fluid molecules. The density distribution, velocity distribution, and temperature distribution of the fluid molecule is analyzed and results are shown.
