The influence of thermal radiation on drying of single droplet/wet particle Academic Article uri icon

abstract

  • A literature review shows lack of the detailed research and discovers contradictions regarding influence of thermal radiation on the drying process of a single droplet, containing solids. The present study shows that for droplet initial diameters< 0.25 mm and ambient temperatures< 750° C, as like as for diameters< 2.5 mm and ambient temperatures up to 200° C, the effect of thermal radiation is negligible. At the same time, for droplets with initial diameter greater than 0.5 mm and temperatures of the drying agent higher than 400° C, thermal radiation plays a substantial part in the drying process.
