These molecular flows are driven by various pressure gradients in nano-sized channels of different heights. The simulations find the existence of layer structures near the wall and the compressibility effect across the nano-sized channel for argon molecules. Slip velocity is obtained and the associated accommodation factor and laminar friction factor are varied with channel size in nano-scale. Furthermore, the flow characteristic in terms of velocity distribution inside nano-channels for different liquid molecules with multi-atoms exhibits very different transport phenomena. In conclusion, the inter-atomic interaction models between liquid atoms or liquid-solid atoms play important roles near interfaces in fluid transport of nano-sized channel flow.Inter-atomic interaction modelsLiquid flow characterizationMolecular dynamics simulationNano-sized channel flowSlip velocityconference paper2-s2.0-6344284554https://www.scopus.com/inward/record.uri?eid=2-s2.0-6344284554&partnerID=40&md5=e1c58cc8ebed63289e1cd6abb5826eb9
