The malfunctioning sewage systems, particularly in wet weather are common in some cities, pollution of receiving waters, sometimes direct consequences of uncontrolled spills, are poorly supported by the natural environment and population. And improving the quality of natural receptors urban pollution through control of finer flows and pollution loads of wastewater systems and especially sewerage. The main objective of this study is three-dimensional modeling of the velocity field with free surface in an overdraft remediation using a three-dimensional isotropic turbulence model unsteady. Detailed understanding of three-dimensional velocity profiles in a pipeline is a precondition to consideration of the transfer of elements of different nature (pollution, solid materials etc ...) in wastewater systems; the model used is based on the model of the system of Navier-Stokes averaged (Reynolds) given the isotropic turbulence model k-ε. A special study was performed after fixing the boundary conditions at the walls and the free surface of the field and a calculation program was developed by our own care. [ABSTRACT FROM AUTHOR] |
