Abstract: Fluid viscosity and molecular diffusion in nanochannels were studied by molecular dynamics simulation. Transport processes in a plane channel, a channel of rectangular cross-section, and in porous media were investigated. The channel height was varied from 2 to 50 nm. The interaction between molecules was simulated using the hard sphere (HS) and the Lennard-Jones (LJ) intermolecular potentials. The porous matrix was modeled by cubic packing of spheres of the same radius, and the packing density and the grain size were varied. The dependence of the transport coefficients on the fluid density and channel characteristics (channel height, channel aspect ratio, porosity of the porous medium, accommodation coefficients, etc.) was investigated.
Description: This paper was presented at the 3rd Micro and Nano Flows Conference (MNF2011), which was held at the Makedonia Palace Hotel, Thessaloniki in Greece. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, Aristotle University of Thessaloniki, University of Thessaly, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute.
