Project: The in-air collision dynamics of complex fluid droplets

This project aims to explore the influence of dynamic fluid properties on microdroplet collision outcomes, particularly relevant in inkjet printing applications. Inkjet printing, known for its precise patterning of microdroplets, faces limitations in ink choice due to printer constraints. Recent advancements bypass these limitations by employing in-air collisions of droplets for synthesis and patterning purposes. While past studies have focused on Newtonian droplets, inkjet fluids pose complexities with phase changes and chemical reactions. The hypothesis suggests that time-dependent properties of complex fluids significantly impact collision dynamics. This project will include both experimental characterisation of model fluids and numerical modelling of collision events. Initial experiments will use non-Newtonian fluids to validate experimental techniques and numerical models. Subsequent experiments will explore fluids exhibiting dynamic properties, such as surface tension variations, with corresponding numerical models. Understanding these dynamics promises insights for optimising inkjet printing processes, especially in rapid chemical synthesis and tissue engineering applications.
