This write-up covers the workflow for simulating these phenomena using FLOW-3D and its coupled modules.
: The model simulates how fluid pressure forces cracks to open, while the opening of those cracks simultaneously changes the fluid's flow rate and pressure. Applications in Dam and Infrastructure Safety Modern 3D Computational Fluid Dynamics (CFD) tools like FLOW-3D HYDRO flow 3d hydro crack top
Traditional physical flumes are expensive and time-consuming to build. 3D CFD acts as a , allowing for: This write-up covers the workflow for simulating these
In the world of hydraulic engineering, few events are as catastrophic as the sudden failure of an embankment dam or levee. When water rises and spills over the crest of an earthen structure, the process of begins — an erosion sequence that can rapidly widen and deepen, leading to uncontrolled releases of reservoir water and devastating downstream flooding. Predicting exactly where and how this breach will start—whether due to a pre-existing crack, a localized weakness at the crest, or a geometric discontinuity on the dam's top—has become a critical area of focus. 3D CFD acts as a , allowing for:
To successfully simulate flow over a crest and analyze potential cracking issues, the following workflow is recommended:
FLOW-3D HYDRO offers a distinct advantage over traditional 2D models. While 2D analyses are faster—potentially 20 times faster than their 3D counterparts—they often miss the turbulent, three-dimensional vertical velocities that characterize the initial "crack top" failure. For small-scale scenarios or specific high-risk projects where precision is paramount, the 3D modeling provided by FLOW-3D HYDRO is not just an alternative; it is a necessity.
Analyzes how solid particles (proppants) are carried into the crack to keep it open.
