The effectiveness parameters analysis for piers scour calculation

Abstract

A computational fluid dynamics numerical model addressed the problem of local scouring and deposition calculation for non-cohesive sediment and clear water conditions near single and double cylindrical piers. The numerical results of single cylindrical piers correlate very well with the physical model's results while are higher than the case of the double pier, especially when the large-eddy turbulence model, the van Rijn bed-load transport equation, and fine mesh size are considered. Additionally, the final numerical predictions are compared to experimental data after parameters effectiveness explores the range of results based on projected user inputs like the bed-load equation, mesh cell size, and turbulence model.

“…It is very important to take into consideration all these factors in order to ensure regular monitoring of the scour phenomenon [7]. In the literature, many equations were developed in order to calculate the depth of the scour ( [5][6][7][8][9][10]) but since they are based on simplified models in laboratories they don't give accurate results. Thus, it was necessary to develop numerical models based on Computational Fluid Dynamics (CFD) in order to calculate the depth of the scour hole and ensure regular monitoring of this phenomenon.…”
