中文摘要

针对室内风生流物理模型匮乏的问题,构建了一套室内模拟风生流的实验系统来模拟不同风速、不同边坡条件下的风生流,并采用PIV测量技术对风生流的流场进行了精密的测量,获取了细致的3维流场信息,同时采用数值方法对实验结果加以佐证。结果表明:该实验系统操作简单,获得的风场稳定,测量结果符合风生流形成规律。此外,数值结果和实验数据基本保持一致,佐证了该实验系统具有模拟风生流的能力。该实验系统也可为今后数值模型的率定和验证提供一种有效的方法。

英文摘要

A physical model was developed to study the wind-driven current in laboratory under the conditions of different wind velocities and different slopes. The wind-driven current in the laboratory was extensively measured by particle image velocimetry (PIV) and accurate field information was got. Furthermore, three-dimensional numerical simulation of the wind-driven current was carried out and the result showed the applicability of the physical model. The results showed that the experimental facility was easy to operate and wind field was stable. The results were accorded with the water body motion law in the wind driven current.
