A three-dimensional Reynolds-averaged Navier-Stokes (RANS) computational fluid dynamics (CFD) model is developed for simulating turbulent mixing in the near-field of thermal discharge at real-life geometrical configurations. The domain decomposition method with the multi-level embedded overset grids is employed to handle the complexity of real-life diffusers as well as to efficiently account for the large disparity of length scales arising from the relative size of the ambient river reach and the typical diffuser diameter.
