Nonlinear shear of entangled polymers from nonequilibrium molecular dynamics (2019)
Journal Article
Anwar, M., & Graham, R. S. (2019). Nonlinear shear of entangled polymers from nonequilibrium molecular dynamics. Journal of Polymer Science Part B: Polymer Physics, 57(24), 1692-1704. https://doi.org/10.1002/polb.24904

This work aims to improve the use of Molecular Dynamics simulations of Kremer-Grest chains to inform future developments of models of entangled polymer dynamics. We perform non-equilibrium molecular dynamics simulations, under shear flow, for well en... Read More about Nonlinear shear of entangled polymers from nonequilibrium molecular dynamics.

Molecular dynamics simulations of crystal nucleation in entangled polymer melts under start-up shear conditions (2019)
Journal Article
Anwar, M., & Graham, R. S. (2019). Molecular dynamics simulations of crystal nucleation in entangled polymer melts under start-up shear conditions. Journal of Rheology, 150(8), https://doi.org/10.1063/1.5082244

Understanding the flow induced crystallisation (FIC) process is necessary due to its technological relevance to polymer processing. Polymer crystallisation controls the morphology of semi-crystalline polymers and hence the properties of the end produ...

Characterising droplet breakup rates of shear-thinning dispersed phase in microreactors (2019)
Journal Article
Wong, V., Loizou, K., Lau, P., Graham, R. S., & Hewkandamby, B. N. (2019). Characterising droplet breakup rates of shear-thinning dispersed phase in microreactors. Chemical Engineering Research and Design, 144, 370-385. https://doi.org/10.1016/j.cherd.2019.02.024

A two-phase flow predictive model with the integration of conservative level-set method (LSM) and Carreau-Yasuda constitutive equation was developed herein. The LSM was chosen as a potential interface capturing scheme for elucidating the interfacial...

Understanding flow-induced crystallisation in polymers: a perspective on the role of molecular simulations (2019)
Journal Article
Graham, R. S. (2019). Understanding flow-induced crystallisation in polymers: a perspective on the role of molecular simulations. Journal of Rheology, 63(1), 203-214. https://doi.org/10.1122/1.5056170

Flow induced crystallisation in polymers is an important problem in both fundamental polymer science and industrial polymer processing. The key process of flow-induced nucleation occurs on a very rapid timescale and on a highly localised lengthscale...
