Professor Alfonso A. Castrejon-Pita obtained his D.Phil. in Physics at the University of Oxford, funded by a prestigious Dorothy Hodgkin Postgraduate award. His research was centred on experimental and theoretical studies of synchronization phenomena in fluids. This was followed by a postdoctoral position in the same laboratory funded by NERC (Natural Environment Research Council, UK) that led to the experimental demonstration of synchronisation of chaos in mutually-coupled fluid flows, with greater implications in atmospheric dynamics such as weather forecast.
From April 2011 to September 2013 he was a Research Associate at the University of Cambridge, and a researcher at St. John’s College, where he redirected his research towards a better understanding of the dynamics of small-scale free surface flows.
Alfonso was awarded a Royal Society University Research Fellowship in October 2013 which he holds at the University of Oxford, where is also an Associate Professor in Fluid Mechanics and a Tutorial Fellow at Wadham College. In Oxford, he established the Fluid Dynamics Laboratory for (mainly) the study of drops and liquid jets. He also supervises the research of MEng, MSc(R) and DPhil students in the Department and in College.
In a new experiment, physicists have shown how to stop droplets of liquid from flying through the air. By lining the lab bench or a surgeon’s instrument tray with soft materials, you can keep the splattering to a minimum.
“Even if you spill a couple of drops, you can be confident they are not going to splash,” says Alfonso Castrejon-Pita, a physicist at the University of Oxford. “The big drop is going to stay as a big drop, and that’s the end of the story.”
Professor Castrejon-Pita’s Fluid Dynamics Laboratory at Oxford focuses on (but is not limited to) the study of drops and liquid jets. Current research activities deal with the breakup of harmonically stimulated liquid jets, drop deposition and splashing dynamics, contact line dynamics, novel droplet generation techniques, and pinch-off of viscous filaments. A variety of novel and traditional diagnostic and imaging techniques such as laser visualisation and velocimetry, shadowgraphy, and high-speed imaging are applied to reveal the complex dynamics of these phenomena. The Laboratory maintains collaborations with groups in the UK, Spain, France, USA, Mexico and Germany.
Their work includes:
The group is currently funded by the Royal Society, the Newton Fund, the John Fell Fund (OUP), and EPSRC.
We study the fundamental fluid dynamics involved in the generation, breakup, coalescence and splash of drops.
This project is devoted to understanding and exploiting the breakup of liquid jets via feedback.
