bead-spring model
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 spring which does not contribute to the frictional interaction but which is responsible for the elastic and deformational properties of the chain. The mutual orientation of the springs is random.
