Designing polymer additives to control breakup of jets and impacting drops. Current agricultural spraying of pesticides is inefficient, causing serious environmental contamination. The project aims to design polymeric additives to control the fluid dynamics of spraying so that drops reach, and then adhere to their target leaf surfaces.
A coupled finite volume method for viscoelastic flow problems on highly-skewed unstructured meshes: a computational rheology revolution. Commercial tools are unavailable for 21st century industry to analyse complex flow processes involving viscoelastic materials. Using fabrication of microstructured polymer optical fibre as a key case study, a coupled finite volume methodology holds the key for the next generation of computational rheology simulators.
