摘要
流场实时测量系统VDMS(以下简称VDMS),是运用数字摄像与粒子跟踪测速技术(PTV)研制开发的表面流场大范围同步测速与监控系统。该系统可快速方便地得到模型试验范围研究区域内的流场、断面流速分布及单个或多个测点的流速矢量变化过程,提高了试验的精度和效率。
Flow field real-time measurement system （called VDMS） is a monitoring system and synchronization measure velocity in large-area surface flow field, utilizing digital camera and particles tracing velocity （PTV） . The system can rapidly and conveniently get the flow field in the model test range, the velocity vector change process of the cross-section velocity distribution and single or mul-tiple points measured, and improved the test precision and efficiency.
