Interfacial interaction between fluid and solid is one of the major factors that affects the fluid transport through a given channel. Hydrodynamic slip length is one of the important parameter to quantify the interfacial interaction. Using molecular dynamic simulation of Poiseuille type flow of Argon fluid through Platinum channel, we have demonstrated a particle method to tune hydrodynamic slip length of nano channels. The effect of varying the interaction potential parameter and roughness ratio on the slip length is reported.
