Abstract
Two-dimensional heat and moisture transfer equations were developed by introducing natural convection and respiratory heat, in order to predict temperature and moisture distribution in grain bed during temporary storage. Though the equations are nonlinear involving natural convective term which requires hydrodynamical calculations, the temperature and moisture distribution can be theoretically calculated by combining both equations. Observed values of temperature and moisture content in the grain bed, which had two layers of different temperature and moisture content, agreed well with the calculated values. Therefore, this method of analysis is considered to be useful for predicting the temperature and moiture distribution in the grain bed.
