摘要
在对近年来流速测量技术的发展历程进行回顾的基础上,着重介绍了激光技术、超声波技术、计算机技术及数字图像处理技术等先进技术在流速测量中的应用及发展,详细分析了悬移质运动中水沙两相流流场测量技术的现状及存在问题,指出综合运用激光诱导荧光技术与粒子跟踪测速技术是实现水沙两相流流场同步测量的一种新途径。
Based on the review of the development of flow measurement techniques in recent years, the application and development of the advanced techniques such as laser, ultrasonic, computer and digital image processing techniques were introduced. The present situation and existing problems of the measurement techniques for water-sediment two-phase flows in transport of suspended load were analyzed. A new approach combined with LIF and PTV for the simultaneous measurement of water-sediment two-phase flows was proposed.
