| 摘 要： | 根据粒子的光散射、散斑成像理论,建立了两相流动粒子相对数量浓度与粒子散斑图像强度之间的线性关系, 通过数字图像分析和处理技术进行污染扩散相对瞬时全场浓度的测量。利用粒子散斑成像测量原理自行设计了大范围瞬时浓度场测量系统,并利用该系统对烟雾扩散的瞬时浓度场进行了实际测量。

| Abstract: | Based on the theories of imaging optics, particle scattering, statistical optics and digital image processing, the mathematical relationship between the quantity concentration of smoke particles of two phase flow and intensity of speckle images is studied. Digital image processing is used to gain the quantificational relative numerical concentration. Using this measurement method and designed system, the instantaneous concentration fields of flows is measured. |
