ABSTRACT
This paper describes a study of droplet transport in high Reynolds number turbulent shear flow. A dilute polydisperse droplet spray was introduced into an axisymmetric disk wake with Re ~ 6 × 105. The Reynolds number and droplet sizes used in this study cover a range of Stokes numbers 5 < St < 500 and a mass loading of 10−2. Data was gathered using a Phase Doppler Interferometer capable of measuring droplet size and 3 components of droplet velocity simultaneously. Results are sorted into 5 ranges of Stokes numbers and include wake profiles of droplet concentration, mean droplet velocity, and the dominant components of the droplet velocity fluctuation covariance.
