A flow wall collision model between two parallel plane walls was established for argon fluid through a microchannel under the condition of action of periodical external force. Based on this model, two kinds of wall (hydrophilic and hydrophobic) were applied on the flow simulations from non-equilibrium molecular dynamics (NEMD). There are 864 fluid particles and wall particles separately in the simulated system. The non-dimension height of microchannel is 9.667. The velocity profile and temperature profile of argon fluid in hydrophilic microchannel predicted by molecular dynamics simulation are in good agreement with the analytical solution based on the Navier–Stokes and energy equations. The velocity profile and the temperature profile experience a large jump in the layers close to the hydrophobic wall.
