Spray evaporation in turbulent flow

Detailed measurements in an isopropyl-alcohol spray issuing into a co-flowing, heated air stream were performed using phase-Doppler anemometry in order to obtain the spatial change of the droplet size distribution and the correlation between droplet size and velocity. Additionally, a reliable method based on the detection of the signal amplitudes was applied to determine the droplet mass flux. By integration of the droplet mass flux profiles, the global evaporation rates could be determined for different flow conditions. Furthermore, numerical calculations of the evaporating spray were performed by the Eulerian/Lagrangian approach. For all the droplet phase properties reasonable agreement with the experiment could be achieved and the global evaporation rates agreed well with the experimental observation.
