Data and Report from S&T Project 1734: Robust Eco-Hydraulic 3D Modeling Tools for Rivers with Complex In-Stream Structures

A new surface embedding method (SEM) is developed and implemented into a 3D computational fluid dynamics (CFD) model U2RANS. The modeling procedure is proposed so that 3D CFD modeling of flows through complex instream structures may be carried out for eco-hydraulic projects. All components of a CFD package to perform the CFD modeling are described. The new capability is described and verified using selected benchmark cases. In specific, a turbulent flow around a cylinder near scoured bed is used to validate the model. Good results are obtained. Further, a complex flow through a six-piece ELJ is used to demonstrate that the model works well even for complex flows. The ELJ case is further lab-tested by collaborators at the U.S. Army Corp of Engineers. The experimental data are further used to validate the model with good comparisons. Additional details of the research have been documented comprehensively in a theory paper (Appendix A) and comparison paper (Appendix B).
