摘要:

The computational study of the rheology of two‐dimensional random cellular systems such as foam or concentrated emulsion systems is presented. The numerical simulations are performed under homogeneous shear using a computationally efficient model in which effects of viscous dissipation inside the liquid films are taken into consideration. It is shown that the system possesses a finite yield stress and behaves like Bingham plastics. The role of the topological change of the cellular structure is also examined.
