Measurement of droplet size, velocity, and temperature distributions in rayleigh flow

Abstract

 Experiments were performed on the droplets formed from a heated, unforced, cylindrical column of water (Rayleigh flow). Temperature distributions, velocity distributions and size distributions were obtained. A thermocouple was used for the temperature measurements. Two time constants were determined – one for the drop impinging on the thermocouple and another for the drop leaving the thermocouple.
