WebApr 10, 2024 · Computational models of Brownian suspensions must be able to accurately reproduce hydrodynamics, thermal fluctuations and mass diffusion. One of the usual targets for simulations is to reproduce the phenomenology observed experimentally in the suspension viscosity when applied shear rate and/or concentration are increased. WebJul 26, 2011 · We consider the Brownian motion of a nanoparticle in an incompressible Newtonian fluid medium (quiescent or fully developed Poiseuille flow) with the fluctuating hydrodynamics approach. The formalism considers situations where both the Brownian motion and the hydrodynamic interactions are important. The flow results have been …
