【 摘 要 】

To develop new drying facilities, it was important to know the impact of every input parameter to the drying process. Using a real prototype to carry out the experiment required high cost and time consuming especially for large scale drying. CFD simulation approached was one of the solution. Previous study of drying simulation only focuses on the fix value of the input parameter. This paper presents the result of CFD simulation to predict the heat distribution in sericite mica drying with variable temperature and airflow condition. Variable temperature and airflow was used because the only heat source for the dryer was from the solar energy therefore it's only available in the day time. The analysis was carried out for 24 hours of drying time. The simulation result shows that the temperature inside the sericite mica increase 8 to 10°C when the solar energy is available and it is still increasing about 4 to 7°C for 5 hours after the solar energy is absent. The result also shows that during the drying time the temperature of sericite mica that is closer to the heat source was higher compared to the one that is further away with the maximum difference of 3.8°C.
