| Abstract: | The 3 D partial parabolic algebraic stress model of turbulence in a bend containing contaminant is established. The turbulent flow structure and contaminant concentration distribution in a bend with no fully developed secondary current are calculated. The calculated profiles of velocity, turbulent energy, dissipation rate, Reynolds stresses and contaminant concentration in the bend are analysed. |
