基于Fluent二次开发的散装水泥运输车卸料过程数值模拟

针对国内散装水泥车罐体设计中不能充分利用流体软件Fluent的情况,利用VB 6.0编程语言编程开发人机交互界面,对Fluent软件进行二次开发,实现散装水泥车罐体卸料过程的数值模拟的专用功能;通过一个实例模拟散装水泥罐车在卸料过程中布风板对卸料过程的影响。结果表明,把Gambit和Fluent内部封装,界面直观、操作简单,能够很好地模拟水泥罐车流态化与卸料过程,并应用到水泥车罐体的开发中;增大布风板的直径能够有效地减少卸料时间,提高卸料效率,并且提高卸料过程的平稳性,在条件允许的情况下应增大布风板的直径。

Numerical Simulation of Bulk Cement Truck Tank Unloading Process Based on Fluent Secondary Development

Aiming at the situation that fluid software Fluent cannot be taken full use of in the design of bulk cement truck tank in domestic,the programming language of VB 6.0 was used to develop man-machine interface for secondary development of Fluent software.The special features of numerical simulation on bulk cement truck tank unloading process were achieved.The effects of air distributor on unloading process in bulk cement truck tank unloading process were simulated by an example.The results indicate that the interface is intuitive and the operation is simple.The fluidized and unloading process of bulk cement truck tank can be well simulated and applied to the development of cement truck tank.Enlarging the diameter of air distributor can reduce the unloading time effectively.The unloading efficiency and the stability of unloading process can be improved.Under the permitted conditions,the diameter of air distributor should be enlarged.
