Members of the Advanced Engineering Centre at the University of Brighton, Dr Steven Begg (Director), Dr Oyuna Rybdylova, Dr Guillaume De Sercey and Mr Zuhaib Nissar travelled to Sweden in February and August to conduct specialist experiments on spray atomisation at the Combustion Physics Division of the Department of Physics at Lund University. The exchanges were supported by awards from the University of Brighton, the Doctoral College PGR Mobilisation and the UKRI Future Leaders Fellowship schemes. Hosted by Associate Professor Edouard Berrocal, Director of the Spray-Imaging group at Lund, the research aims to improve fundamental understanding of sprays, essential to many clean energy, environmental and medical applications. The Brighton team transported their custom test rig and research equipment to Lund to conduct state-of-the-art optical measurements, including ultra-high-speed microscopic imaging of a spray with the unique KIRANA camera from Specialised Imaging, at frame rates up to 7 million images per second at full frame resolution. Photographic, fluorescence and SLIPI image data acquired during the experiments is beginning to provide new insights into liquid breakup dynamics and droplet formation that supports more accurate, predictive computational fluid dynamic models currently being developed at the Advanced Engineering Centre. The groups look forward to forging long-term collaborative partnerships and will present their findings at the European ILASS conference in September https://en-gb.eu.invajo.com/event/lunduniversity/ilasseurope2025
