A model simulating the hydrodynamic properties of a chain macromolecule consisting of a @ST06775@ of beads, each of which offers hydrodynamic @R05315@ to the flow of the surrounding medium and is connected to the next bead by a rigid rod which does not. The mutual orientation of the rods is random.
