Many analyses of temperatures in stored grain had been reported using boundary condition such as the changes in only ambient air temperature. In this study, the grain in cylindrical bin was regarded as the infi nite cylinder, and the equation for predicting the grain temperatures was given as the partial differential equation in which respiration heat of the grain was considered. In the equation, it was assumed that heat flow was only in the radial direction.
The above equation was solved by the finite differences approximation using digital computer.
Computing the above equation, the following boundary condition was applied; it was outer wall temperatures of grain bin which was calculated in relation between the ambient air temperatures estimatimated by means of Monte Cairo methods and the heat gain with solar radiation and/or the heat loss with long wawe radiation at the surface of bin wall.
The predicted grain tewperatures were compared with the observed.
