Description: A finite difference model of heat transfer was developed to predict temperature distributions in the radial, verticaland circumferential directions of free-standing, cylin drical, grain storage bins. This three dimensionalmodel can predict temperatures using the input data of initial grain temperature, ambient air temperature, solar radiation on a horizontal surface, wind velocity, and thermal properties of grain, bin wall, concrete, soil and air. Tem peratures in a 5.56-m-diameter bin containing rapeseed to a depth of 2.7 m were simulated using the model, for a 41 month period. Pre dicted temperatures were in good agreement with measured temperatures at 16 locations in the bin. Temperatures for the north and south facing parts of bins, predicted by the three dimensional model were distincdy different from those predicted by a two dimensional model.
