Distribution of time average velocity in wave - current combined flow 波浪和水流共同作用下水流时均流速分布
The turbulent flow in open channel is tested with laser - doppler anemometer , in which the longitudinal time average velocity and fluctuating velocity of turbulent flow in open channel under the conditions of the sudden changes of roughnesses at different water depths are measured 摘要通过激光测速仪,对壁面糙率突变时的明渠紊流进行试验,测量了糙率突变不同水深情况下明渠紊流的纵向时均流速和脉动流速。
