Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   Computational Fluid Dynamics (CFD) and Computational Multiphysics Modeling (CMM) analysis procedures that will be developed, or further developed, include analysis of flood and wave forces on bridges; scour around bridge foundation structures, individually and in combination; scour countermeasures; bridge designs that minimize vulnerability to scour; culvert analysis, including flow losses in different culvert barrel geometries and surfaces; ease of fish passage; effects of bed material on scour, including cohesive sediment and sediment of varied size; effects of debris on scour; live bed scour; and other processes that may impact the safety of the transportation system or minimize adverse affects of the transportation system on the environment. The Transportation Research and Analysis Computer Center (TRACC) facility at the Argonne National Laboratory will be utilized for the modeling.
Goals:   Computational Fluid Dynamics (CFD) and Computational Multiphysics Modeling (CMM) hydraulic modeling will generate additional test results to develop new design procedures for highway hydraulic research problems that will be incorporated into Federal Highway Administration (FHWA) publications, such as Hydraulic Engineering Circular No. 18, "Evaluating Scour at Bridges."
Product Type:   Research report
Test Methodology:   There is a need to further develop and validate an advanced three-dimensional, unsteady, Computational Fluid Dynamics (CFD) model capable of quantitatively accurate predictions for hydraulic hazards. Lagrangian and Eulerian models of sediment transport under clear water conditions have brought novel insights into the erosion and scour processes. Such insights include establishing computationally the multifractal nature of the bed load flux, and demonstrating the ability of the Eulerian model to predict the emergence of statistically meaningful bed forms inside the scour hole. This research will also identify major computational challenges for further advancing high-resolution computational models and point to the knowledge gaps into the fundamental physics of the scouring process that need to be filled from experiments.
Expected Benefits:   The expected benefit is that the Computational Fluid Dynamics and Capability Maturity Model modeling will enhance highway hydraulic design procedures.
