摘要(Abstract):

对应用于褐煤提质系统中的离心风机进行了数值模拟。使用Fluent6.2软件,先在AutoCAD中进行几何建模,导到Gambit中划分区域,采用三角形网格进行离散处理,采用合理的湍流模型来描述,将计算结果应用于相应公式计算其效率,并与褐煤提质系统中的实测数据进行了比较,得出了较为可信的结论,对于褐煤提质系统的实际应用提供了可靠的条件。
Raise the quality of the lignite used in the centrifugal fan system was simulated.Use fluent6.2 software,first conducted in AutoCAD geometric modeling,leading to the gambit in the area,dealing with discrete triangular grid,using a reasonable model to describe the turbulence,the calculation formula used to calculate the corresponding efficiency and and lignite and quality and system testing data,and obtains a more reliable conclusion,for the lignite to mention the practical application of quality system provides a reliable conditions.
