Original Report by Revealer | Presented by Agile Device
At the 2025 Chinese Society of Engineering Thermophysics Annual Conference held in Beijing, Agile Device showcased Revealer High Speed Cameras, sCMOS Cameras, and Bubble Measurement Software, highlighting their crucial roles in combustion diagnostics and multiphase flow research.
These optical instruments are revolutionizing how researchers visualize transient thermal–fluid processes that were once impossible to capture with traditional imaging systems.
2.1 In-Chamber Combustion Visualization
Closed-chamber combustion — such as in pre-chamber igniters, internal combustion engines, or detonation tubes — involves complex shock–flame–boundary interactions within confined, unsteady reactive flows.
Using the Revealer High Speed Camera operating at 10,000 frames per second with microsecond-level shutter control, researchers can record ignition, flame propagation, and pressure wave reflection inside the chamber.
This high-temporal-resolution visualization provides valuable experimental data for studying combustion stability control in next-generation propulsion and power systems.
2.2 Blue Flame Dynamics in Fire Safety Research
In fire safety engineering, flame propagation characteristics directly affect hazard assessment and mitigation.
The blue flame, characterized by complete combustion and high temperature, plays a key role in understanding flame propagation kinetics.
Conventional imaging sensors with quantum efficiency below 30% often fail to capture such weak-light phenomena.
By contrast, Revealer sCMOS Cameras — featuring quantum efficiency above 95% and ultra-low readout noise — can precisely detect the blue flame contours, extract flame-front position data, and compute propagation velocity across sequential frames.
This enables quantitative analysis of flame dynamics even under extremely low-light conditions.
3.1 Bubble Dynamics and Flow Structure Characterization
Multiphase flow studies focus on the motion, deformation, and interactions of bubbles, droplets, and particles, which govern heat transfer, mass transfer, and chemical reaction efficiency.
Capturing these rapid interfacial dynamics is challenging due to complex boundary evolution and high temporal variation.
By combining Revealer High Speed Cameras with Bubble Measurement Software from Agile Device, researchers can extract bubble contours, compute Sauter mean diameter distributions, and evaluate bubble area, velocity, and acceleration.
The system quantitatively describes bubble dynamics and provides new insights into multiphase flow structures and instability mechanisms.
High Speed Cameras, sCMOS Cameras, and Bubble Measurement Software from Revealer and Agile Device have become indispensable tools in combustion and multiphase flow research.
These technologies make the invisible visible — capturing blue-flame propagation, bubble evolution, and transient reactive flow phenomena with unprecedented clarity.
By delivering high-sensitivity, high-speed visualization, they empower scientists and engineers to overcome long-standing experimental challenges in combustion stability, multiphase transport, and reactive flow modeling.
