Multi-scale modelling describing thermal behaviour of polymeric materials. Scalable lattice-Boltzmann models based upon the theory of Grmela towards refined thermal performance prediction of polymeric materials at micro and nano scales.

摘要

Micrometer injection moulding is a type of moulding in which moulds have geometricaluddesign features on a micrometer scale that must be transferred to theudgeometry of the produced part. The difficulties encountered due to very high shearudand rapid heat transfer of these systems has motivated this investigation into theudfundamental mathematics behind polymer heat transfer and associated processes.udThe aim is to derive models for polymer dynamics, especially heat dynamics, thatudare considerably less approximate than the ones used at present, and to translateudthis into simulation and optimisation algorithms and strategies, Thereby allowingudfor greater control of the various polymer processing methods at micrometer scales.
