Abstract
The thermal state of the rice mass in steel vertical silo with an aeration system, located in a rice storage facility in Rio Grande do Sul State, Brazil, was studied. The experimental data obtained by thermometry system were compared with the predicted data obtained by the mathematical model proposed. The model presents the system of two partial differential equations, describing the heat transfer and conservation of energy for air and for grain mass. The proposed model satisfactorily describes the thermal state of the studied silo. The use of the last data reading as a new initial condition increases the simulation accuracy. In the case of a significant transverse temperature inhomogeneity, a hypothetical ivision of the silo into independent vertical cylinders centered on the respective cables permits to increase the accuracy.
