Theory of polymer dynamics

WebbMolecular dynamics simulations of a dense melt of short bead-spring polymer chains containing N = 5, 10, or 25 effective monomers are presented and analyzed. Parts of our simulations include also a single dumbbell (N = 2) of the same type, which is interpreted to represent a coarse-grained model for a fluorescent probe molecule as used in … Webbinvigorated me to derive a free volume theory of polymer dynamics that will be discussed in the forthcoming sections of this PhD thesis.

WebbTo solve problems in polymer fluid dynamics, one needs the equations of continuity, motion, and energy. The last two equations contain the stress tensor and the heat-flux vector for the material. There are two ways to formulate the stress tensor: (a) One can write a continuum expression for the stress tensor in terms of kinematic tensors, or (b) one … WebbA system such as a polymer displays many dynamic modes.
