Subject: LDA/PDA

The flow field of liquid in two dimensional and three dimensional models of horizontal primary oil/water separators has been studied experimentally using LDA and PDA measurement techniques.

Нашла несколько определений. В данном контексте это будет Лазерная доплеровская анемометрия (Laser Doppler Anemometry) и Анализ динамики частиц (Particle Dynamics Analysis)??
please confirm :)))))))))

thanx

LDA, это я согласен, а от PDA... Может это - ... in any fluid mechanics laboratory where the laser Doppler (LDA) or !!! phase Doppler (PDA) techniques !!! are used.

И это тоже:
In the last two decades laser Doppler
anemometry (LDA) and

!!!!!!!!!phase Doppler anemometry (PDA)!!!!

were used for this purpose. LDA and PDA are both
point techniques and therefore quite time-consuming to apply. Planar light sheet techniques like particle image
velocimetry (PIV) and Doppler global velocimetry (DGV) offer much higher data rates.

да, вообще это более логично... :))
пасибо, Задорожний!
