Research

Paste, Particle and Polymer Processing group

Understanding and developing models to predict the flow patterns generated by impinging liquid jets. The work is driven by the wide use of impinging liquid jets as components of cleaning-in-place (CIP) systems to distribute cleaning solutions and rinsing liquid around the walls of tanks, reactors and other process vessels.
