Friction coefficients of axisymmetric particles in suspension

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 particle, valid in the long-particle limit. Some particular examples are under scrutiny namely, the case of particles of regular form and the influence of end effects and the roughness of the particles in the dynamics. The first one serves to illustrate our method whereas the second to manifest its applicability to open problems in the dynamics of objects in suspension.
