摘要
针对非接触测量技术在航空发动机燃烧室气动热力领域的发展及应用现状,对基于激光的先进光学诊断试验技术及其他非接触测量技术进行了综述.光学可视模型燃烧室试验件主要有旋流杯光学模型燃烧室和分区分级耦合燃烧室两大类,其设计需要考虑燃烧室本身特点、研发目标等问题;对于航空发动机燃烧室,LDV、PIV和HTV技术常用于流场速度的测量,LDV、PDPA和PLIF/Mie技术在气液两相流及雾化特性测量中发挥了重要的作用,CARS、TDLAS、PLIF和SRS技术广泛应用于燃烧场温度、组分浓度的测量.其他非接触测量技术如超声波测温法、辐射测温法、红外测温法等很好地弥补了光学测温存在的缺陷.未来非接触测量技术需要根据探测对象的要求和特点优势互补,以更好的满足未来航空发动机燃烧室对非接触测量的需要.
Abstract
According to the development and application of non-contact measurement technology in aero-engine combustor,the advanced optical diagnostic test technology based on laser and other non-contact measurement technologies are reviewed.There are two main types of optically accessible model combustor test pieces:swirl cup optical model combustor and staged combustors combining premixed and diffusion combustor.The design needs to consider the characteristics of the combustor itself and the research and development goals.For aero-engine combustor,the LDV,PIV and HTV technologies are commonly used to measure the flow field velocity.The LDV,PDPA and PLIF/Mie technologies play an important role in the measurement of gas-liquid two-phase flow and atomization characteristics.The CARS,TDLAS,PLIF and SRS technologies are widely used in the measurement of combustor field temperature and component concentration.Other non-contact measurement technologies such as ultrasonic temperature measurement method,radiation temperature measurement method and infrared temperature measurement method can well make up for the defects of optical temperature measurement.The future non-contact measurement technology needs to complement each other according to the requirements and characteristics of the detection object,to better meet the needs of non-contact measurement of the future aeroengine combustor.
