This study addresses the challenge of developing effective strategies to prevent and control the deterioration of stored grain quality caused by biological activities and heating. The unclear mechanisms of water migration and humidity distribution within rice grain piles subjected to localized high temperatures complicate this effort. Using COMSOL simulation and model granaries, the study examines temperature fields, humidity fields, and water migration in high temperature and humidity areas. Results show that within 24–48 h of high-humidity r...
