燃烧室热声振荡压力脉动特性测试方法

1范围

本文件描述了燃烧室热声振荡压力脉动特性的测试原理和方法选择、测试流程、测试条件、数据处

理和测试报告。

本文件适用于航空发动机、地面燃气轮机、火箭发动机、工业炉、燃气具等能源动力装置与设备的

燃烧室热声振荡压力脉动特性的测试。

2规范性引用文件

下列文件中的内容通过文中的规范性引用而构成本文件必不可少的条款。其中，注日期的引用文

件，仅该日期对应的版本适用于本文件；不注日期的引用文件，其最新版本（包括所有的修改单）适用于

本文件。

GB/T18696.2声学阻抗管中吸声系数和声阻抗的测量第2部分：传递函数法

GB/T37650燃烧方式术语和定义

GB/T45573气体燃料燃烧室的振动等级评价及测量方法

3术语和定义

GB/T37650、GB/T45573、GB/T18696.2界定的以及下列术语和定义适用于本文件。

3.1

压力脉动pressurefluctuation

燃烧室内瞬时压力相对于其时间平均压力的偏差。

3.2

热声振荡thermoacousticoscillation

燃烧室内非定常释热与声场相互耦合产生的自我维持的周期性压力脉动现象。

注：热声振荡源于热释放波动与声场脉动之间形成的满足瑞利准则的正反馈机制，表现为由一种或多种热声模态

主导的振荡。

3.3

引压管pressuretube

连接动态压力测量点与传感器的传压管。

3.4

半无限长引压管semi-infinitepressuretube

实际长度有限，利用管内声学衰减特性消除末端反射波影响，从而在声学特征上模拟无限长管路

的引压管。

3.5

引压孔pressurehole

燃烧室壁面上与引压管连接的传压孔。

3.6

压力脉动频率pressurefluctuationfrequency

单位时间内燃烧室压力脉动的循环次数。
