Abstract: | This study proposes a method to solve low speed (<1 ms?1) flow of water in silica nanochannels. The conventional MDS method has difficulty to determine the small flow velocity because the nonlinear coupling of the small bulk flow velocity with the large peculiar velocity of the thermal motion. The new method can overcome this difficulty and extract the true flow velocity caused by external forces at each time step. The distributions of velocity, density and temperature are investigated for high and low speed cases. |
