从控制压气机性能的停滞压力通量的角度，分析和数值研究了涡量动力学在轴向压气机诊断和设计中的作用。滞压通量主要受周向涡量分布的影响。周向涡量可以用循环分布直接表示，是通流压缩机设计中的重要参数。提出了一些控制压气机性能的原理，并以两个动叶为例，采用通流法设计，用三维雷诺-平均纳维-斯托克斯数值模拟对其进行了验证。ASME版权所有©2007
The role of vorticity dynamics in the axial compressor diagnosis and design is investigated analytically and numerically, in terms of the stagnation-pressure flux that controls the compressor’s performance. The stagnation-pressure flux is found to be dominated by the distribution of circumferential vorticity. The circumferential vorticity is directly expressible by the circulation distribution which is the significant parameter in the throughflow compressor design. Some principles of controlling compressor performance are thereby proposed, which are demonstrated by two rotor blades, designed by throughflow procedure and evaluated by three-dimensional Reynolds-average Navier-Stokes simulation.Copyright © 2007 by ASME
