Abstract: By using the software of Airpak, unsteady air flow and heat transfer in a drying room used for containers are simulated with two different schemes of air supply. The transient numerical solutions are obtained for air flow within the drying room, including flow speed, pressure, temperature, mean age of air, etc.. The analysis focuses on temperature field distribution, temperature rise, and the mean age of air surrounding the container surface changing with heating time. Two air supply schemes are that scheme one with air inlets located on the ground under the container and scheme two with just air inlets raised into the container, the rest of factors remaining unchanged. Calculation results show that comparing with scheme one, in scheme two, the temperature field distribution is evener, temperature raises more quickly, and the mean age of air is smaller, especially in critical places where it is difficult to dry. It could be concluded from the results that scheme two is the scheme that should be selected for better drying quality, shorter drying time, and less energy consumption.
