Numerical simulation of separated turbulent flow using GAO-YONG turbulent model

  • 摘要: 采用GAO-YONG湍流模式对二维管道内三角形钝体绕流问题以及槽道内后台阶分离流动进行了数值模拟.求解程序基于开源数值计算平台OpenFOAM (Open Field Operation and Manipulation),数值模拟结果很好地预测了钝体绕流问题中漩涡脱落的尾流的流动趋势以及后台阶流动中分离再附的流动结构,同时分析了速度分布以及摩擦系数等参数并与实验值进行了对比,结果符合很好.这表明GAO-YONG湍流模式对大分离流动有较好的预测能力,对工程实践具有指导性作用.
