Analysis of a viscoelastic phase separation model
Aaron Brunk, Burkhard Dünweg, Herbert Egger +3
A new model for viscoelastic phase separation is proposed, based on a systematically derived conservative two-fluid model. Dissipative effects are included by phenomenological visc…
Universal scaling and characterisation of gelation in associative polymer solutions
Aritra Santra, B. Dünweg, J. Ravi Prakash
A Brownian dynamics algorithm is used to describe the static behaviour of associative polymer solutions. Predictions for the fractions of stickers bound by intra-chain and inter-ch…
Shear thinning in dilute and semidilute solutions of polystyrene and DNA
Sharadwata Pan, Duc At Nguyen, B. Duenweg +3
The viscosity of dilute and semidilute unentangled DNA solutions, in steady simple shear flow, has been measured across a range of temperatures and concentrations. For polystyrene…
Energy-stable linear schemes for polymer-solvent phase field models
Paul J. Strasser, Giordano Tierra, Burkhard Dünweg +1
We present new linear energy-stable numerical schemes for numerical simulation of complex polymer-solvent mixtures. The mathematical model proposed by Zhou, Zhang and E (Physical R…
An improved dissipative coupling scheme for a system of Molecular Dynamics particles interacting with a Lattice Boltzmann fluid
Nikita Tretyakov, Burkhard Dünweg
We consider the dissipative coupling between a stochastic Lattice Boltzmann (LB) fluid and a particle-based Molecular Dynamics (MD) system, as it was first introduced by Ahlrichs a…
Equilibrium binding energies from fluctuation theorems and force spectroscopy simulations
Emma Hodges, B. M. Cooke, E. M. Sevick +3
Brownian dynamics simulations are used to study the detachment of a particle from a substrate. Although the model is simple and generic, we attempt to map its energy, length and ti…
