Macroscopic thermodynamics of flowing polymers derived from systematic coarse-graining procedure

摘要: Abstract Macroscopic thermodynamics of flowing polymeric liquids in terms a single conformation tensor is derived from atomistic or mechanical bead-spring models via systematic coarse-graining procedure. The macroscopic equations here are consistent with earlier works where they have been proposed on more phenomenological grounds. present approach provides microscopic justification these including expressions for the transport coefficients. In addition, consider second-order dissipative processes that arise due to cross-correlated fluctuations variables and insofar offer an extension previously chosen level description.
