IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Numerical simulation of borad-crested weir flow using a mesh-free method
Author : TIBING XU (1) & YEE-CHUNG JIN (2)
ABSTRACT
Moving Particle Semi-implicit method (MPS), as a mesh-free method, has been applied to model many applications.
Moving particles are used to replace fixed meshes in traditional methods. The advantage of this method is that the free
surface can easily and automatically be identified in complex surface problems during calculation due to its Lagrangian
nature. A turbulence model, derived from Large Eddy simulation (LES), has been implemented in MPS to model turbulent
flows, such as jet flow, and open channel flow over a sill. The broad-crested weir is one type of water discharge
measurement devices used in hydraulic engineering. In this study, a broad-crested weir flow is modeled by using MPS
with the turbulence model. Numerical results were compared with experimental measurements with respect to freesurface
profiles and horizontal and vertical velocity profiles. Good agreements have been achieved between the numerical
and experimental results.
