Bubble dynamics
Our research group has been established for more than 30 years and is recognised as a world leader in the mathematics of bubbles. 
Research interests
- Multi-scaled modelling of bubble dynamics in compressible and viscous liquid
- Bubble dynamics near a rigid boundary, a free surface, an interface between two liquids and/or other bubbles, at a corner, inside a tube or fully confined domain, subject to buoyancy or ultrasound
- Physical, mathematical and computational studies of cavitation generation
- Kelvin impulse theory
- Bubble jetting, topological transition of bubbles and toroidal bubble dynamics
- Energy loss of a bubble system due to the emission of shockwaves and viscous effects
- Cavitation cleaning of implant teeth using ultrasonic scaler
- Underwater explosion bubbles
- Drug delivery using encapsulated microbubbles and ultrasound
- Analytical modelling of spherical bubbles and encapsulated microbubbles
- Stability analyses of bubbles and encapsulated microbubbles
