Processes on different length scales affect the dynamics of chain molecules. In this work, we focus on structures on the scale of a monomer and investigate polyolefins, i.e., hydrocarbon chains with different small-scale architectures. We present an exact enumeration scheme for the simulation of interactions and relative motion of two short chain sections on a lattice and employ it to deduce th...

This paper investigates the impact of small-scale unsteadiness on adjoint-based output sensitivity analysis. In particular, when iterative methods for nonlinear flows fail to converge to a steady state, it is demonstrated that the resulting sensitivity analysis can be highly inaccurate, evenwhen the unsteadiness in the outputs is small. The specific example considered is the viscous subsonic fl...
