Abstract

In this paper, the k-e’ TWO-EQUATION TURBULENCE MODEL has been used to simulate ice accumulation under ice cover along a river bend. A 2D depth-averaged numerical model has been developed in a NONORTHOGONAL COORDINATE SYSTEM with nonstaggered curvilinear grids. In this model, the contravariant velocity has been treated as an independent variable. To avoid the pressure oscillation in the nonstaggered grids, the momentum interpolation has been introduced to interpolate variables at the interface. The discretization equations have been solved by using pressure correction algorithms. An equation has been developed for describing the deformation of ICE JAM bottom. The thickness distribution of ice accumulation (ice jam) along the bend has been simulated. The developed model has been applied to the experimental studies under different conditions carried out at the Hefei University of Technology. Results indicate that all simulated thickness of ice accumulation agrees reasonably well with the measured thickness of ice accumulation in laboratory.
