Article   M. Kröger, A. Alba, M. Laso, H.C. Öttinger
Variance reduced Brownian simulation of a bead-spring chain under steady shear flow considering hydrodynamic interaction effects
J. Chem. Phys. 113 (2000) 4767-4773
In order to obtain numerical estimates for the properties of a general model for polymers in dilute theta solutions in its long-chain limit we follow a stochastic approach to polymer kinetic theory. The model takes into account configuration-dependent hydrodynamic interaction (HI) and simplifies to the Zimm bead-spring chain model in the limit of preaveraged HI, for which parameter-free `universal ratios' such as the ratio between radius of gyration and hydrodynamic radius are known. The Chebyshev polynomial method and a variance reduction simulation technique is used to implement an efficient Brownian dynamics simulation. We resolve the full dependence of several characteristic ratios vs. both chain length and hydrodynamic interaction parameter, we extrapolate their values to determine universal behaviors, and compare with analytical and experimental results.
