Mathematical Model of a Flash Drying Process

The paper presents a basic model of the flash drying process, as it is applied in a number of industrial appliions, and illustrates this by means of a particular appliion: the drying of subbituminous coal. Besides its economic importance, that appliion is representative of those where the product is combustible, so that the drying needs to be conducted in an inert atmosphere, which is ...
