We study the dynamics of an axisymmetric particle suspended in a fluid. The approach we use is based on the induced forces method. We then obtain formal expressions for the friction tensors from which one derives explicit formulas for the friction coefficients depending on the shape of the...

In a fluid in elongational flow the diffusion of tagged particles differs from the same process in an equilibrium fluid. The diffusion coefficient becomes direction, frequency, wave vector and elongation rate dependent. In the context of nonequilibrium fluctuating hydrodynamics explicit...
