Experimental estimation of evaporation rates of water droplets in high-temperature gases

Resumo

Evaporation rates of water droplets in high-temperature gases were experimentally determined using high-speed video recording cameras and low-inertia thermocouples (for heated air flow as an example). The experiments were carried out for droplets of initial size (radius) 1–3 mm at an air temperature of 500–1000 K. Dependences of the evaporation rate of water droplets on time and gas temperature were obtained for various initial droplet sizes.
