Effect of Temperature Sensor Numbers and Placement on Aeration Cooling of a Stored Grain Mass Using a 3D Finite Element Model

Grain stored in silos the United States of America is generally cooled with an aeration system to limit mold spoilage and insect infestation. Monitoring efficacy real-time conditions grain done using temperature cables fixed-spaced sensor locations that are hung from roof silo. Numerous placement options exist terms number their positions. However, little investigation has been into effects cable on operation decisions monitoring conditions. For a one-year period, temperatures predicted by sensors three recommended configurations were evaluated for Ames, IA, USA. The average each lower than entire silo, as much 11.4 °C difference. When used inputs control, all similar temperatures. averages varied 3.6 depending distribution chosen. Results demonstrated near center or edges produce results not representative mass, resulting less efficient aerations. Simulations also conducted randomized horizontal “wireless” at fixed depths. similar, but increase reduced variability between simulated storage years increased.
