COSI Research Collaborations

Note: The COSI Network has now closed, and has been replaced by the Evolving Interfaces in Complex Flows Special Interest Group of the UK Fluids Network. This website is being maintained as an archive, so the information it contains is not necessarily up to date.

Some highlights from research collaborations between members of the COSI network are described below.

Free surface flows driven by the motion of solid bodies

Numerical simluation of the time evolution of a liquid surface impacting on a moving inclined boundary.

John Billingham (Nottingham) and David Needham (Birmingham) have collaborated extensively on free surface flows driven by the motion of solid bodies. This has been supported by a multi-institution responsive mode grant from EPSRC (ended 2014).

Falling Multilayer Film Flows

Mark Blyth (UEA) and Jamal Uddin (Birmingham) have recently collaborated on falling multilayer film flow with particular application to curtain coating. Working with PhD students Julian Thompson (UEA) and Dominic Henry (Birmingham), they have developed stability theory and carried out experiments (these were conducted by Thompson and Henry at KAUST in collaboration with Jeremy Marston).
