| description | In this paper a numerical study of urban flooding caused by dam break has been undertaken. Problem statement: This study illustrated the influence of the different versions of K-epsilon turbulence model on the water flow behavior, predicted by Computational Fluid Dynamic (CFD) and validated through experiment. Approach: The water velocity, free surface profile and also secondary circulation flow along with the pressure through the city are simulated and proved. Results: Results are obtained with numerical simulation using standard k-epsilon, are relatively good agreement with the experimental results. Conclusion/Recommendations: In the present study, the velocity and the water depth are investigated to check the real capabilities of a 3D numerical code ANSYS-CFX and especially to define the optimal parameters (Mesh, boundary conditions, turbulence model,) able to simulate the flow behavior through the complex urban area, with the best accuracy. |
