Arbitrary flow boundary conditions in smoothed dissipative particle dynamics: A generalized virtual rheometer

In this work, a methodology to perform rheological studies on smoothed dissipative particle dynamics under arbitrary flow configurations is introduced. To evaluate the accuracy and flexibility of proposed methodology, viscometric for Newtonian fluids pure shear, extension, flows in bulk or near walls are The applicability obtain viscoelastic properties non-Newtonian fluids, such as polymer solutions, also presented. new computational approach offers relevant advantages variety applications ranging from multiscale simulations characterization complex flows.
