| 中文摘要: |
| 本文应用一种考虑湍流－旋流相互作用及湍流脉动各向异性的新的代数Ｒｅｙｎｏｌｄｓ应力模型，对环形通道内的湍流旋流流动进行了数值模拟，研究了改主为旋流流数，进口轴向速度及半径比等参数对环形通道内湍流流动的影响，以及对强化环形通道内传热的作用。 |
| 英文摘要: |
| 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. |
