场地膜秆分离装置送风口尺寸改变的数值模拟

A Membrane Separation Device Size Change of the Numerical Simulation of Air Supply Outlet

为达到有效分离地膜的目的,建立了场地膜秆分离装置的三维计算流体力学模型,采用Fluent软件对场地膜秆分离装置内的流场进行数值模拟分析,改变分离装置送风口的几何尺寸,分析比较其内部流场的压力分布速度分布。结果表明:在送风口和进料口的相对位置为100mm、送风口宽度为200mm和送风口长度为6 0 0 mm时最为合理,为场地膜秆分离装置的结构设计和性能改进提供了参考。

In order to reach the goal of effective separation membrane,the establishment of a membrane separation device of three- dimensional computational fluid dynamics model,the fluent software is adopted to a membrane separation device within the flow field numerical simulation analysis,the change of geometry size,air supply outlet of comparative analysis of its internal stress distribution of the flow field velocity distribution,concludes that the relative position of air supply outlet and inlet is 100 mm,the width of air supply outlet is 200 mm,and the most reasonable air diffuser length is 600 mm. For a membrane separation device for the structure design and performance improvement.
