摘要
粒子图象测速PIV(Particleimagevelocimetry)技术是一种新型的流场测试技术 ,既能测得流场速度的大小 ,又可获得速度的方向。本文通过对PIV技术的物理模型的讨论和根据高流速流场的测量的需要 ,提出并设计了实时可调数字脉冲同步器 ,实现跨场技术 ,并应用到实际流场的流速测量中 。
PIV(Particle Image Velocimetry)technology is one of novel measurement technology applied in fluid field.Not only the magnitude but also the direction of velocity of fluid field can be obtained through PIV.In this paper according to the discussion of the physical model of PIV and the demand of measuring high speed flow field,Adjustable Digital Pulse Synchronizer was approached and designed.Through the very technology not only was the field straddling technology realized but the better result was obtained when applied into the real flow field.
