Numerical Simulation of Flow around Two Rotation Cylinders in Tandem Configuration

  • 摘要: 串列旋转双圆柱绕流现象在自然界和工程实践中十分常见,基于fluent采用非结构网格有限体积法对具有旋转速度的串列双圆柱绕流进行了数值模拟,研究了不同间距及不同旋转方式下的流动特性,得出了相关的气动性能,给出了串列旋转圆柱的升阻力系数的变化规律。计算表明:上下游圆柱均顺时针旋转且间距为3.0时圆柱升阻比较大,为较优的排列旋转方式。研究结果对航空、航海及其相关领域的工程问题有实际意义。

     

    Abstract: It is a common problem in nature and the engineering practices that the flowing phenomenon of the two rotating tandem cylinders. Based on finite-volume method in unstructured grid, the flow around two rotation cylinders in tandem configuration by fluent software and the aerodynamic performance of different spaces and different rotation modes were investigated. Concurrently, we reached a relevant aerodynamic performance and variations of coefficient of lift and drag of cylinders. the results showed that it is a better way that the upstream and downstream cylinder are clockwise rotating and the spacs is 3.0,whose lift-drag ratio is higher,which have practical significance to the engineering problems in aviation, navigation and related fields.
