本文将超声速度剖面法（UVP）成功地应用于非均匀磁场作用下液态金属通道流动的研究。利用超声波测速仪测得的速度分布及其数值后处理，有效地生成了二维时均流场图。使用直接浸入工作流体中的单个换能器，以简化测量线的对准并避免声束在壁上的不期望的折射。将磁障碍物后的M型流动和尾迹重建为剪切流和大尺度旋涡流。
An ultrasonic velocity profile (UVP) method has been successfully applied to the investigation of a liquid metal channel flow under the influence of an inhomogeneous magnetic field. Using velocity profiles obtained by the ultrasonic velocimeter and their numerical post processing, two-dimensional time-averaged flow maps were efficiently produced. A single transducer immersed directly into the working fluid was used in order to simplify alignment of measurement lines and avoid the undesirable refraction of the acoustic beam on the walls. An M-shaped flow and wake behind a magnetic obstacle were reconstructed as the patterns of shear and large-scale vortical flows.
