结合火焰辐射与互相关法的燃烧颗粒速度测量方法研究
Combined flame radiation and cross-correlation method for velocity measurement of burning particles
摘要
Abstract
For online velocity measurement problem of high temperature burning particles, the measurement method which combines flame radiation and cross correlation method is presen-ted,and the measurement device has been designed to measure the velocity of burning pulverized coal particles in the flat flame burner experimental system.The two upstream and downstream measuring points at a distance of 6 mm are set to obtain the flame radiation signals of burning par-ticles.The velocity is determined from the cross-correlation analysis of the two signals.Thus, the time evolution of particle velocity under different conditions is obtained.Compared to the results of computational fluid dynamic,the relative deviations have been found to be less than 10%.The result shows that this method can provide a simple and effective method for measuring the burning particle velocity in the harsh environment such as coal combustion in a boiler and pro-pellant combustion in a solid rocket motor.关键词
