Moreover, the simulation results show that the effect of triangle roughness surface on the flow behavior is more than the cylindrical ones. Results also show that the maximum density near the wall for a rough surface is less than a smooth wall. In fact, by increasing the roughness ratio (height to base ratio), the slip velocity and the maximum velocity in the channel cross section are reduced, and the density fluctuations near the wall increases. Results show that surface shape and roughness height have a decisive role on the flow behaviors. The effects of surface roughness geometry, gap between roughness elements (or roughness periodicity), surface roughness height and surface attraction energy on the behavior of the flow undergoing Poiseuille flow are presented. The Lennard–Jones potential is used to model the interactions between all particles. Density and velocity profiles across the channel are investigated in which roughness is implemented only on the lower wall. Numerical simulation of Poiseuille flow of liquid Argon in a rough nano-channel using the non-equilibrium molecular dynamics simulation is performed.
