摘要
喷注器的喷雾质量直接影响推进剂在燃烧室中的燃烧效率。为了准确获得其喷雾特性,以收集法、PDA及PIV为代表的喷雾场测试技术一直在不断发展和完善中,其中PIV技术与数字全息技术相结合发展的DHPIV技术具有较好的应用前景。对近年来的喷雾场测试技术进行了综述,介绍了各种测试技术的原理、特点及其在喷雾场测试中存在的问题。
The injector spray quality influences the liquid propellants combustion efficiency directly. To get a comprehensive understand of the spray characteristics, many diagnostic techniques for measurements have been put forward and updated. DHPIV is assumed to be a promising technique for spray measurements. This paper reviews different techniques for spray measurements during the recent years, including the principles, characteristics and issues in spray measurements of the techniques.
