| 摘要: |
| 基于结构网格动态面搭接技术、五阶Roe-WENO格式求解非定常RANS方程,开发了用于旋转类问题非定常流动数值模拟的计算分析程序,并针对典型旋转类算例进行了分析验证。对Caradonna-Tung旋翼的计算结果表明:计算得到的旋翼桨叶表面压力分布与实验值吻合良好,计算程序可以用于旋翼悬停、简单前飞状态的气动力数值模拟与分析;同时在计算网格分布相同情况下,五阶Roe-WENO格式较三阶Roe-MUSCL格式对于旋翼尾迹的分辨率更高,计算得到的旋翼桨尖涡尾迹更加清晰。对螺旋桨机翼干扰问题的研究结果表明,所开发的计算程序对于刚性旋转类问题非定常流动数值模拟具有很好的适用性,对于尾迹的捕捉具有较高的精度,满足工程实际应用的要求。 |

| Abstract: |
| A computational analysis procedure, which based on structure dynamic patched grid, the fifth-order Roe-WENO scheme and unsteady RANS method, was developed for the numerical simulation of the unsteady flowfiled of the rotor. Typical rotor examples were analyzed to verify the reliability of the procedure. Calculation results of the Caradonna-Tung rotor show that the calculated pressure distribution of the rotor is in good agreement with the experimental values. The developed procedure can be used for the numerical analysis of the aerodynamic performance of the rotor in hover or forward flight. In the case of the same computational grid distribution, the fifth-order Roe-WENO scheme has a higher resolution for the simulation of the rotor's wake than that of the third-order Roe-MUSCL scheme and the wake of the tip vortex can be captured more clearly. The results of the propeller wing interference show that the developed procedure has good applicability for the unsteady simulation of the rigid rotation type of problem. The procedure developed by this paper has high accuracy of wake vortex simulation, it can meet the requirements of engineering applications. |
