Numerical investigation of flow in pool-and-weir fishways using a meshless particle method
Tibing Xu,Yee-Chung Jin +1 more
TL;DR: In this paper, a new solid boundary treatment using imaginary particles instead of traditionally predefined ghost particles is developed to accommodate sharp edges in addressing practical problems, which is verified for a sharp-crested weir flow, and then applied to simulate flow in pool-and-weir fishways with thin walls.
