RÉSUMÉ

Spray absorption efficiency is a function of the surface area of drops, interaction between the drops, oscillations, coalescence, and breakup. Knowledge of drop size distributions is critical for estimating the total surface area of drops and hence the rate of absorption. This paper illustrates a unique facility designed to measure drop size and velocity distributions using a phase Doppler interferometer (PDI) through dense wall flow. A novel eyepiece insert facilitated PDI measurements through liquid films running down the inner wall of the glass chamber. Measurement data with water as the test fluid with and without countercurrent gas flow is presented.
