We characterize the flow field near the star polymer as a function of its functionality (arm number) f . A strong screening of the imposed flow is found inside the star polymer, which increases with increasing f . To elucidate the importance of hydrodynamic screening, we compare results for hydrodynamic and random solvents. The dependence of the polymer orientation angle on the Weissenberg number shows a power law behavior with super-universal exponent --independent of hydrodynamic and excluded-volume interactions. In contrast, the polymer rotation frequency changes qualitatively when hydrodynamic interactions are switched on.}, keywords = {Computer Simulation / Diffusion / Elasticity / Microfluidics / Molecular Conformation / Movement / Physics: methods / Polymers: chemistry / Shear Strength / Software / Solvents: chemistry / Stress, Mechanical / Viscosity / Polymers (NLM Chemicals) / Solvents (NLM Chemicals) / J (WoSType)}, cin = {IFF-2 / JARA-SIM}, ddc = {530}, cid = {I:(DE-Juel1)VDB782 / I:(DE-Juel1)VDB1045}, pnm = {Kondensierte Materie}, pid = {G:(DE-Juel1)FUEK414}, shelfmark = {Chemistry, Physical / Materials Science, Multidisciplinary / Physics, Applied / Polymer Science}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:17712520}, UT = {WOS:000249461500002}, doi = {10.1140/epje/i2006-10220-0}, url = {https://juser.fz-juelich.de/record/58131}, }
