Simultaneous heat and mass transfer under natural and forced convection.

The evaporation of liquid drops into a gaseous medium is of considerable theoretical and practical interest. It is involved in a growing number of industrial processes such as spray drying, cyclone evaporation, spray crystallization, combustion of liquid fuels, and evaporative cooling, to cite only a few. It also represents the basic operation in a new high-temperature solids-gas contacting method called the Atomized Suspension Technique (1, 2, 3) in which a finely divided suspension of droplets can be passed very rapidly through a sequence of physical operations (such as evaporation and drying) followed by chemical reaction, in a single piece of equipment
