Abstract  This paper provides a methodology developed for the calculation of the feed rate and of the exit air conditions in an adiabatic rotary dryer, which operates with granular, nonporous solids having only unbound surface moisture. Some aspects related to the algorithm are also discussed in greater detail, such as the behavior of the wetbulb temperatures along the dryer and the selection of initial …

numerical modeling ofa cocurrent cascading rotary dryer
Jul 01, 2016 · Similar to the model developed by Thorpe (1972), the cocurrent rotary dryer is axially divided into n fixed control volumes of length L/n, where L is the total length of the dryer. A schematic of a control volume is shown in Fig. 1.In order to conduct steady state heat and mass balances on each section of the cocurrent dryer, the following assumptions were made:
