Abstract

The article presents a mathematical model, numerical simulation results, and experimental investigations of heat- and mass-transfer processes, and the operating parameters of an experimental spraying plant for dehydration of concentrated solutions with convective–radiant energy supply. The article shows that the heat- and mass-transfer processes, dryer capacity, and evaporated moisture performance can be enhanced by reducing the specific heat consumption due to the impact of infrared radiation on the liquid spray plume area and the creation of a countercurrent vertical flow mode of the coolant.
