Computer simulation of non-Newtonian fluid rheology
Dissipative Particle Dynamics (DPD) is a new simulation technique that focuses on intermediate time and length scales. With this technique it is possible to simulate the essential aspects of the rheological behavior of polymeric liquids quite efficiently. Model studies show that DPD reveals the expected shear thinning and normal stress effects. We also show that the effects of thermodynamic solvent quality on the configurations and rheological behavior of dissolved polymers can be studied with the DPD model.
