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.

Features

  • Non intrusive
  • Can measure in dense sprays
  • On-line, real time results
  • Simultaneous size and velocity of each droplet or particle
  • Interferometric technique, requires no calibration
  • No prerequisite assumptions on size and velocity distributions 
  • One, two or three velocity components simultaneously
