We investigated the spinning process of a polymeric material by using a multiscale simulation method which connects the macroscopic and microscopic states through the stress and strain-rate tensor fields, by using Lagrangian particles (filled with polymer chains) along the spinning line. We introduce a large number of Lagrangian fluid particles into the fluid, each containing Np-Hookean-dumbbells to mimic the polymer chains (Np=$10^4$), which is equivalent to the upper convected Maxwell fluid… 

Multiscale Simulations of Flows of a Well-Entangled Polymer Melt in a Contraction–Expansion Channel

We have successfully applied a multiscale simulation (MSS) method [Murashima, T.; Taniguchi, T. Europhys. Lett. 2011, 96, 18002] to flows of a monodispersed linear entangled polymer melt in a

Rheology and Entanglement Structure of Well-Entangled Polymer Melts: A Slip-Link Simulation Study

We have extended the slip-link model originally developed by Doi and Takimoto [Philos. Trans. R. Soc. London, A 2003, 361, 641] to calculate fast shear and uniaxial elongational flows. The original

Learning the constitutive relation of polymeric flows with memory

The proposed learning/simulation approach is expected to be used not only to study the dynamics of entangled polymer flows, but also for the complex dynamics of other Soft Matter systems, which possess a similar hierarchy of length- and time-scales.

Multiscale simulation of history-dependent flow in entangled polymer melts

Predicting the flow of an entangled polymer melt is still difficult because of its multiscale characteristics. We have developed a novel multiscale simulation technique to investigate the

We present an extensive molecular‐dynamics simulation for a bead spring model of a melt of linear polymers. The number of monomers N covers the range from N=5 to N=400. Since the entanglement length

The dynamic rheology of a polymer melt composed of short chains with ten beads between rapidly oscillating plates is investigated for various oscillation frequencies by using the hybrid simulation of the molecular dynamics and computational fluid dynamics to find that the fractional amplitude of the higher harmonics to the linear harmonics is suppressed within the boundary layer due to the nonslip boundary on the oscillating plate.
