| 摘 要： | 为了检验环境风洞浓度场测量系统的可行性和可靠性,以及对所设计的环境风洞浓度场测量系统的误差进行分析和研究,本文发展了一种通过定量加浓的方法来检验该测量系统。检验试验是在水中加入标准粒子,利用加入粒子的浓度不同来进行测量。试验结果表明对于所提出的基于数字图像的相对浓度场测量方法正确,设计的浓度场测量系统可行、合理.

| Abstract: | In order to verify the feasibility and reliability of environment wind tunnel concentra- tion measurement system,analysie and study the error of the concentration measurement system,a new verification experimental method through measured standard reference concentration solution was described in this paper.In experimental water tank the various standard reference solutions that dif- ferent special standard particles were added in water was provided.The concentration field of standard reference solution was measured by concentration filed measurement system.The concentration field and measurement error were acquire by digital image processing software.The results show that the concentration field measurement system based on digital image processing is feasible and reasonable. |
