超声衰减与光散射法蒸汽液滴粒径和含量对比测试
Measurement of steam droplet size and content：a comparison of ultrasonic attenuation and light scattering
摘要
Abstract
A steam generation and measurement experimental system was developed. Combined with a theoretical expression of the classical ECAH (Epstein-Carhart-Allegra-Hawley) model, a tri-frequency method was proposed to measure the droplet size and content (volume fraction) using ultrasonic attenuations, where center frequencies of ultrasonic waves were 22, 40 and 200 kHz respectively. As a comparison, experiments based on multi-wavelength light extinction method and laser scattering method were carried out , both of which were both based on the principle of light scattering. The results show that the measured particle size and content (volume fraction) using the ultrasonic attenuation method are relatively close to the light extinction and the laser scattering method. Ultrasonic attenuation method is also expected to realize on-line measuring of the particle size and content (wetness) of steam in the gas-liquid two-phase flow.关键词
