Models, Methods and Software Development of Contaminant Transport in Meandering Rivers
This paper reports a tentative computation aiming to investigate flow and contaminant transport in meandering river. The developed quasi-3D hydrodynamic model is closed by both turbulence depth-integrated κ-ε model and κ-w model, respectively. The advanced SIMPLE (Semi- Implicit Method for Pressure-Linked Equation) algorithm for FVA (Finite Volume Approach), ILU (Incomplete Lower Upper) decomposition, PWIM (Pressure Weighting Interpolation Method), SIP (Strongly Implicit Procedure), under relaxation and multi-grid iterative method have been used to solve the fundamental governing equations, discretized on non-orthogonal boundary- fitted collocated grid. Except for steady flow and pollutant side discharge, the processes of pollutant inpouring and plume development at the beginning of discharge have been numerically investigated.
