High - resolution acoustic doppler velocimeter

将水、废水和工业废水排入河流和小溪等明渠一直是一种常见的做法。模拟这些流动系统以及相关的沉积物和污染物的运移的能力对于理解此类排放对环境的影响至关重要。在大多数情况下，流动是湍流的，这意味着发生的混合和冲刷主要是由于流体的小尺度混沌行为。为了更好地理解和控制上述流动/过程，速度场的知识是必不可少的。温莎大学正在进行上述几个领域的研究。流速测量装置是研究水流的重要仪器。为此，需要一台声学多普勒测速仪（ADV）来同时测量河床冲刷和沉积物运动的流速。

It has been a common practice to discharge water, wastewater and industrial effluents into open channels such as rivers and streams. The ability to model these flow systems and the associated transport of sediments and pollutants is of critical importance in understanding the environmental impact of such discharges. In most cases, the flows are turbulent, which means the mixing and scour that occurs is largely due to small-scale chaotic behaviour of the fluid. To better understand and control the above mentioned flows/processes, knowledge of the velocity field is an essential ingredient. Research in several of the above-metioned areas are in progress at the University of Windsor. An essential insturment in researching the flows is a velocity measuring device. To this end, an accoustic Doppler velocimeter (ADV) is being requested to measure the velocity of the flow simultaneously with scouring of the bed and movement of sediment.
