Profile

I am a member of the EPSRC Centre for Doctoral Training (CDT) in Fluid Dynamics. My research project is in the dynamic surface tension in inkjet printing.

Research interests

One focus of my PhD project is the effect of dynamic surface tension and in particular the role of key active components, such as surfactants, and their effect on drop formation in the jetting process. The rapid expansion of the free surface during jetting means that local areas of surface will be depleted of surfactants leading to surface tension gradients. In this project we will develop a fluid dynamics model that incorporates these effects.

During the first year of CDT programme, I worked on a interdisciplinary MSc team project, which considers the settling behaviour of colloidal suspensions. This kind of behaviour can lead to phase separation of the system. We proposed an improved model to describe such systems with this kind of behaviour while we investigated the problem with highly controlled laboratory experiments. Consumer products such as e.g. Lenor and Downy, usually use this problem and hence many applications of this model can be seen in this area. During this project, I visited the P&G's European Technical Centre, the Brussels Innovation Centre in order to conduct many experiments.
