| 摘 要： | 掺有碘分子的流动流体,在激光的作用下会产生感应的荧光发射,激光感应的碘分子荧光包含有压强的信息,采用成像法,得到的是压强场在一个平面上的分布,因而这一测量是多点测量。作者测量了压强对激光感应的碘分子荧光的影响,去除喇曼散射引起的散射峰,提出了直接利用激光感应的荧光测量流动流体的压强场的非接触测量新方法,还探讨了这一方法的理论和实验方案。

| Abstract: | Flow fields seeding molecular iodine induced by laser would emit fluorescence, which contains the information of pressure . Through image-intensified detection,the pressure fields distributed on a plane is measured .thoroughly a multiple-point measurement.The influence of pressure on fluorescence of molecular iodine induced by laser is measured. If the scatter peak resulted from Raman scater is discarded,a new nonintrusive measurement method by means of the laser-inducing fluorescence for a direct measurement of the pressure field in the flowing fluid. |
