The three - dimensional numerical simulation of temperature and moisture in grain heap in warehouse during cooling ventilation with ＂F＂ layout was conducted based on computational fluid dynamics theory. The movement of temperature and moisture inside of grain heap was obtained and compared with the real measurement.
