...A. S. Ziarani; A. A. Mohamad A molecular dynamics simulation of flow over two side-by-side cylinders with atomically rough surfaces is presented. The model is two-dimensional with 3 × 10 5 liquid argon atoms. The surface roughness is constructed by external protrusion of atoms on the surface...

... and argon respectively. It can be found that the speed of the gas with lighter molecular mass is much higher than that of the heavier gas. The computational domain of the parallel microchannel was established similarly to that of the series microchannel. Under a certain pressure ratio, more pressure drop...
