摘要
为优化气体引射器的结构设计方法,针对引射器部分结构参数进行了室内模拟试验。在给定气源参数的基础上,利用气体动力函数法设计引射器基准型试验装置,分别研究喷嘴距、吸入口直径、混合段直径与喷嘴出口直径之比以及混合段长度对引射器性能的影响。试验结果给出了结构参数对气体引射器性能的影响规律,具有一定的工程应用价值。
To optimize the design method of the gas ejector structure,indoor simulation experiment was given on part of the structural parameters of the ejector.On the basis of the given gas source parameters,the benchmark test device was designed according to aerodynamic function method.The effects of nozzle position,inlet diameter,mixing section diameter and nozzle exit ratio and mixing section length on ejector performance were studied respectively.The experimental result,which reveals how structural parameters impact the performance of the gas ejector,has certain engineering application value.
