Abstract
Mathematical modeling and computer simulation of grain drying are the major emphasis of grain drying research in CAU (China Agricultural University). Since 1988, research on simulation of concurrent flow, counterflow, cross-flow, and mixed-flow grain dryers has been accomplished. The developed mixed-flow grain drying software has been used in analysis of dryer performance, design, and optimization of new grain dryers and management of existing ones. Effect of size, shape, number of rows, and arrangement of air duct on the performance of a mixed-flow grain dryer has been studied.
