چکیده:

This Paper presents simulation of electroosmotic phenomenon in nanochannels using the dissipative particle dynamics (DPD) method. Most of the last electroosmotic studies in nanochannels have been concentrated on the continuum Newtonian fluids. In reality, there are many nano/microfluidic applications in analyzing bio-fluids, which may not be categorized in continuum Newtonian fluid flow studies. In such applications, it is very important to control the fluid flow rate. Therefore, it is necessary to know how the Newtonian fluid behaviour differs from the non- Newtonian one. In this paper, we simulate the electroosmotic flow in mesoscopic scale using the DPD method. The results show that there is a complex behaviour of velocity profile governed by the non-Newtonian fluid in various conditions. The current numerical results are in very good agreement with other available results.
