| Abstract: |
| A new algebraic Reynolds stress model,which properly accounts for turbulence\|swirl interactions and non\|isotropic turbulence, is employed to numerically simulate swirling turbulent flows in an annular duct. The calculated results delineat the effects of swirl number, inlet axial velocity, and ratio of inner to outer radius on the annular swirling turbulent flows. The subsequent effects on enhancing heat transfer in the annular duct, due to the variations in these parameters, are also discussed. |
