一种明渠流泥沙起动全流场同步测量系统及方法
By reconstructing the three-dimensional concentration field through a multi-view image acquisition system and iterative algorithms, the limitations of spatial dimension and phase resolution of traditional two-dimensional measurement methods have been overcome. This has enabled the simultaneous measurement of the three-dimensional full flow field and multiphase flow of the sediment initiation process, providing key data support for sediment initiation.

AI Technical Summary
Traditional two-dimensional measurement methods cannot obtain key information on the three-dimensional vortex structure and multiphase flow during sediment initiation, making it difficult to accurately measure the interaction force between sediment particles and water flow, and also unable to simultaneously measure the motion velocity of each phase in the same spatiotemporal coordinate system.
A multi-view image acquisition system, combined with a high-energy continuous laser and a high-speed camera, is used to reconstruct the three-dimensional concentration field and motion trajectory through MART or SART iterative algorithms, calculate the three-dimensional velocity field and velocity slip, and analyze the spatiotemporal correlation between vortex structure and particle initiation.
It achieved three-dimensional full measurement of the flow field during sediment initiation, accurately quantified the interaction of multiphase flows, and provided data support for the critical conditions and microscopic mechanisms of sediment initiation.
