Abstract: AbstractDissipative Particle Dynamics (DPD) is a fairly new method for simulating complex fluid flows and other colloidal phenomena. In this thesis, a new implementation of the no slip boundary condition in the modeling of solid boundaries is studied. After that, the effects of two important DPD parameters (particle density and conservative coefficient) are studied. Furthermore, to confirm the ability of DPD method to provide numerically accurate results in simulating complex flow with rather complicated boundary conditions, this method is employed to study the flow behavior of three dimensional microscopic concentric/eccentric flows at finite Reynolds numbers. A simple DPD fluid (made up of simple DPD particles) and then bio-molecular suspensions (FENE chains are used to model DNA macromolecules) are studied in detail respectively.Keywords: Dissipative particle dynamics; Simulation; Numerical analysis; Concentric/eccentric annular flow
