机载式相位多普勒干涉仪在结冰风洞的应用

为提高喷雾系统雾化喷嘴的性能,提出一种在结冰风洞云雾参数中用机载式相位多普勒干涉仪(phase Doppler interferometer-flight probe double range,PDI-FPDR)测试粒径特性的方法.介绍PDI-FPDR系统的原理和应用条件,给出结冰风洞喷雾系统在不同水压和气压条件下的试验测量结果,并对结果进行初步分析和对比.试验结果表明:该测试方法有效、可靠,可为结冰风洞云雾特性研究提供依据.

Application of PDI-FPDR in Icing Wind Tunnel

For improving atomizing nuzzle performance of atomizing system, the measurement method of the particle size of phase Doppler interferometer flight probe double range in icing wind tunnel is introduced. The principle and application conditions of PDI-FPDR system were introduced. The test results of icing wind tunnel spray system under different water pressure and pressure conditions were given. Preliminary analysis and comparison about test result. Test result shows that the test method is effective and reliable, which provides a basis for the study of cloud characteristics of icing wind tunnel.
