Spray analysis

Characterizing high-velocity spray plumes requires ultra-short exposure times (sub-microsecond) and high optical magnification to eliminate motion blur and freeze microscopic droplets in flight. Our rental setups combine high-sensitivity cameras, specialized macro/telecentric lenses, and pulsed backlighting designed for advanced Shadowgraphy and Particle Tracking.

• Primary Atomization & Jet Breakup: Visualizes the liquid core directly at the nozzle orifice, capturing Kelvin-Helmholtz instabilities, turbulent surface waves, and ligament separation as fluid leaves the tip.
• Droplet Sizing & Velocity Distribution: Enables high-resolution shadowgraph imaging to quantify droplet trajectories, dispersion velocity, and size distributions (SMD) across dense spray fields.
• Plume Morphology & Spray Cone Angle: Records macroscopic plume propagation, cone symmetry, and temporal pulsation to evaluate cyclic repeatability in fuel injectors, aerosol valves, and agricultural nozzles.
• Secondary Breakup & Aerodynamic Shear: Tracks how surrounding gas shear forces stretch, bag-break, or strip larger droplets into sub-micron mist particles in cross-flow and high-pressure chambers.
• Surface Impingement & Wall Wetting: Captures dynamic spray impact on hot or cold surfaces, analyzing droplet rebound, crown splash mechanisms, and thin liquid film deposition in combustion chambers or coating systems.
