Dissipative particle dynamics (DPD) for modeling complex flows requires proper boundary conditions to simulate the behavior of a wall-bounded flow. Although most DPD simulations use the no-slip boundary condition, slip should be considered for a more complete and realistic description of such flows. The present work suggests a new wall model, via a wall-particle virtual velocity approach, to impose tunable partial-slip boundary conditions while structuring a modified reflection mechanism to enforce the no-slip boundary condition. The new wall model is validated through simulating the planar Poiseuille and Couette flows and implemented to investigate the wall slip status affected by the wall virtual velocity.
