Phase Doppler Anemometry
Phase Doppler Anemometry
Dantec Dynamics’ Phase Doppler Anemometry (PDA) (also known as Particle Dynamics Analysis or PDPA) systems measure the size, velocity and concentration of spherical particles, droplets or bubbles suspended in gaseous or liquid flows.
A very common application is the analysis of atomized liquids (sprays) in e.g. fuel injection, spray painting, liquid metal spray and pharmaceutical sprays.
Applications
- Spray and liquid atomisation
- Bubble (cavitation) dynamics
- Particle transport (painting, coating, etc.)
- Fuel injection
- Pharmaceutical sprays
- Inkjet printing
Features
- Non intrusive
- On-line, real time results
- Interferometric technique, requires no calibration
- One, two or three velocity components simultaneously
- Can measure in dense sprays
- Simultaneous size and velocity of each droplet or particle
- No prerequisite assumptions on size and velocity distributions
