Imposing Lees- Edwards Boundary Conditions in Dissipative Particle Dynamics
摘要
Abstract
Considering the cell subdivision method and the modified velocity- Verlet algorithm, the implementation of Lees-Edwards boundary conditions for DPD method was investigated. The simulated results show that the profiles of velocities, densities, temperatures, pressures and stresses agree well with the expected. Furthermore, when dissipative coefficient y was increased to 100, the velocity profile in the system was homogeneous, indicating that the LE boundary conditions still valid for higher dissipation rate. Viewpoints different from Ref [21] are proposed.关键词
