I'll talk about a computational methodology called the Stokesian dynamics. This method is solving many-body problems in fluids (solutions) in the limit of short length scale (the Stokes approximation), where the viscosity is the dominant contribution. Although it was developed primarily for micro-scale physics like colloidal dispersions, it is also useful for the nano physics when we try to approach from the larger side. Unfortunately, according to the relative complexity, the hydrodynamic interaction is often ignored or replaced by a simple model, but it is rather important for nano scale phenomena, especially nanofluidics, for example. I'll give a brief summary of hydrodynamics and the numerical methods and hopefully show some preliminary results of the nano-scale applications.
