  • In order to solve the obvious phenomenon of temperature and moisture stratification caused by vertical ventilation in squat silos, based on the theory of porous media flow and heat and mass transfer, the flow and temperature distribution in grain stacks under radial ventilation in squat silos were studied by using computational fluid dynamics (CFD).The velocity, temperature distribution and ventilation resistance of radial ventilation at different grain storage heights in squat silos were obtained.The ventilation effect of radial and vertical ventilation in squat silos at different grain storage heights were analyzed and compared with those of full-orifice panels at the same grain loading heights.The results of this study could provide a theoretical basis for the selection of mechanical ventilation systems in squat silos.
