华东工学院在国内首次用激光干涉技术获得了火箭发动机的真实燃射流的近场的流谱。验证和修正了有关理论计算结果与冷射流模拟的纹影流谱图,为燃射流及其它燃烧、喷流等瞬态流场的研究提供了优良的测试手段。
East China Institute of Technology for the first time in China using laser interferometry technology to obtain the rocket engine’s real jet stream near-field flow spectrum. The results of the theoretical calculation and the simulation of the cold jet flow are validated and corrected, which provides an excellent test method for studying the jet flow and other transient flow fields such as combustion and jet flow.
