| 摘 要： | 为提高过热蒸汽流化床干燥模型的模拟精度，该文基于过热蒸汽流化床干燥机理，结合“双流体”理论建立了描述过热蒸汽流化床干燥过程的非稳态轴对称二维数学模型。利用有限体积法求解模型，模拟研究了常压下油菜籽的过热蒸汽流化床干燥过程及其干燥动力学特性，模拟结果与试验数据相吻合。研究结果表明，该模型能够很好地描述常压下油菜籽的过热蒸汽流化床干燥过程和物料在干燥过程中的运动状态。

| Abstract: | In order to improve the precision of superheated steam fluidized bed drying model,an unsteady axisymmetric two-dimensional model was established based on the drying mechanism of superheated steam fluidized bed drying and Eulerian-Eulerian theory to simulate the process of superheated steam fluidized bed drying and the distributions of some parameters in this paper.The finite volume method was applied to solve the mathematical model.It showed that the simulated drying dynamic characteristics were coincidence... |
