  The numerical simulation of a Poiseuille flow in a narrow channel using the
molecular dynamics simulation (MDS) is performed. Poiseuille flow of liquid
Argon in a carbon nanochannel is simulated by embedding the fluid particles in
a uniform force field. Density, velocity and Temperature profiles across the
channel are investigated. When particles will be inserted into the flow, it is
expected that the dynamics of flow will depend on the thermostat chosen. To
obtain a more uniform temperature distribution across the channel we use local
thermostating near the wall. The obtained results show that velocity profile,
slip length and slip velocity depends on the driving force.
