Particle, Bubble & Droplet Characterisation
- Particle Analysis

PARTICLE • BUBBLE • DROPLET
Understand what is happening inside your multiphase system.
Experimental characterisation of particle, bubble and droplet populations using imaging, image analysis and engineering data.
Experimental measurement and analysis of particles, bubbles and droplets to determine size, distribution, shape and behaviour across multiphase systems. Our characterisation methods can be adapted to different particle, bubble and droplet systems.
- Particle size and morphology
Measurement of particle dimensions, shape and distribution from experimental images. - Bubble size and distribution
Characterisation of bubble populations, including size distributions and changes under different operating conditions. - Droplet size and distribution
Measurement of droplet populations to investigate formation, dispersion and separation behaviour. - Population analysis
Statistical analysis of individual features to provide a more representative understanding of the system than a single average value. - Behaviour under changing conditions
Comparison of particle, bubble and droplet characteristics across flow rates, fluid properties, geometry and other experimental parameters.
METHODOLOGY
A measurement workflow designed around the requirements of your application.
01: Capture: High-resolution images are collected from the experimental system using an appropriate imaging configuration.
02: Detect: Image processing is used to identify individual particles, bubbles or droplets within the captured images.
03: Characterise: Measured features are converted into size, shape, frequency and distribution data.
04: Analyse: The results are statistically analysed to identify trends and relationships between operating conditions and particle, bubble or droplet behaviour.
05: Interpret: Experimental findings are connected to the underlying engineering problem and can be used to support design, optimisation or numerical modelling.
ENGINEERING APPLICATIONS
Characterisation across multiphase systems
01: Water & Wastewater: Bubble and droplet characterisation for separation, treatment and aeration processes.
02: Oil & Gas: Investigation of dispersed phases, droplet formation and separation behaviour.
03: Aquaculture: Characterisation of bubbles and microbubbles used in aeration and water treatment systems.
04: Chemical Processing: Analysis of particle and multiphase behaviour within process equipment.
05: Research & Development: Experimental datasets for research programmes, model development and validation.
06: Equipment Development: Characterisation data to support prototype development, testing and design decisions.
ENGINEERING & ANALYSIS
Connect physical measurements with engineering models and design decisions.
• Experimental Imaging: High-resolution imaging for particle, bubble and droplet systems.
• Image Analysis: Identification and measurement of individual features within experimental images.
• Statistical Analysis: Size distributions, population characteristics and experimental trends.
• Multiphase Flow: Interpretation of particle, bubble and droplet behaviour within multiphase systems.
• CFD & Population Balance Modelling: Experimental measurements can be used to support CFD and population balance model development and validation.
• Engineering Design: Characterisation results can inform equipment design, process development and prototype evaluation.
