Effect of angular momentum conservation on hydrodynamic simulations of colloids.

摘要: In contrast to most real fluids, angular momentum is not a locally conserved quantity in some mesoscopic simulation methods. Here we quantify the importance of this conservation flow fields associated with different colloidal systems. The field analytically calculated and without for multiparticle collision dynamics (MPC) method, simulations are performed verify predictions. generated around particle moving under an external force slip boundary conditions depends on momentum, amplitude friction substantially affected. Interestingly, no dependence found colloids influence phoretic forces. Moreover, circular Couette between no-slip cylinder investigated, which allows us validate one two existing expressions MPC stress tensor.
