Our research primarily focuses on studying the dynamics of raindrops and viscosity-stratified flows. We developed a unique experimental facility that mimics the dynamic atmospheric conditions of raindrops descending from cloud to ground. Our other study addresses mixing, a key feature in most modern industrial processes.

Research Areas

1. Raindrops: Accurate rainfall prediction is one of the grand challenges in environmental research due to its relevance in understanding climate change and its accompanying socio-economic impacts, but it is far from perfect. Our research provides important information on the three-dimensional shape, velocity, and size distributions of raindrops for weather forecasting and enables more accurate rainfall prediction.

2. Bubble dynamics: Despite being a classic subject that has intrigued scientists for centuries, we were the first to produce a regime map demarcating different bubble rise behaviours, including the previously unknown break-up bubbles.

3. Stratified flow: We illustrated how viscosity variation in space and time could profoundly and unexpectedly alter fluid flows. Our study contributed to the comprehension of core-annular pipe flows relevant to the oil and gas industries.
