Journal of Fluid Mechanics Webinar Series: Outi Supponen, ETH Zurich, Switzerland

The Leeds Institute for Fluid Dynamics is delighted to partner with the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, the UK Fluids Network, and the Journal of Fluid Mechanics to deliver a regular webinar series on fluids-related topics.

The autumn edition of the Fluid Mechanics Webinar Series will take place over ten weeks between 2nd October and 4th December 2020. Registration will remain open, and please note that if you have already registered you need not register again.

Video recordings of past webinars will be made available soon. Watch this space!

Speaker: Outi Supponen, ETH Zurich, Switzerland

Date/Time: Friday 30th October, 2020. 4:00 pm BST/11 am EDT

Title: The curious dynamics of bubble oscillations and collapse

Abstract: Bubbles oscillate under the effect of pressure fluctuations, such as those produced by sound waves. When driven into a violent collapse, they can yield strong sound emissions, high-speed jets, and extreme heating - a behaviour known as cavitation. In this lecture, we will present ongoing research efforts to reach a fundamental understanding of the intriguing dynamics of bubbles and the resulting flows, combining ultra-high-speed experiments with theory. The broad aim of this research lies in the quest for harnessing their power for a variety of engineering applications, including ultrasound diagnostics, drug delivery, sonochemistry, surface cleaning and micro-fluidics.
