中文摘要:

转子定子相互作用在一台接近音速的轴的压缩机驾驶的不稳定的流动可变性的数字调查被执行。有在转子和定子排之间的靠近、远的轴的差距的二个模型在模拟被学习。特别注意被纳入涉及驾驶转子的机制的分析弄醒摆动,转子醒来扭曲并且流动在转子出口的角度变化。更小的轴的差距是有利的在在二邻近的排之间的区域提高相互作用的结果表演,和转子的方面弄醒的二之间的静态的压力差别的变化从在定子下面由潜在的地被改进,它是为转子的驱动力醒来摆动。在转子和定子之间的相互作用被增加轴的距离削弱,转子与转子沥青的5%10%弄醒移动到转子片的吸方面,在转子出口的流动角度的绝对值是不到那在靠近的间隙星际为的情况中每次走,并且变化振幅也被减少。

英文摘要:

Numerical investigation of the unsteady flow variability driven by rotorstator interaction in a transonic axial compressor is performed. Two models with close and far axial gap between rotor and stator rows are studied in the simulation. Particular attention is attached to the analysis of mechanisms involved in driving rotor wake oscillation, rotor wake skewing and flow angle fluctuation at rotor exit. The results show that smaller axial gap is favorable to enhance the interaction in the region between two adjacent rows, and the fluctuation of the static pressure difference between two sides of rotor wake is improved by potential field from down stator, which is the driving force for rotor wake oscillation. The interaction between rotor and stator is weakened by increasing axial distance, rotor wake shifts to suction side of rotor blade with 5%-10% of rotor pitch, the absolute value of flow angle at rotor exit is less than that in the case of close interspace for every time step, and the fluctuation amplitude is also decreased.
