The Application of Mathematical Model and Numerical Simulation in the Pneumatic Drying of the Straw
According to the analysis of the characteristics of the biomass straw in its pneumatic drying process, some reasonable assumptions concerning the pneumatic drying are made and the mathematical model of heat and mass transfer in the biomass straw’s pneumatic drying process in the horizontal straight tube. Besides, the numerical method is adopted to solve the model and the analog simulation concerning the moisture content, temperature and the speed changes of the material and the air is conducted. Meanwhile influence of the gas-solid ratio and the air flow’s initial temperature on the drying effect is the analog simulated and the reason for this phenomenon is also analyzed.
