本文首先提出一个新的‘人工来流振荡’模型,在此基础上建立了跨声速叶栅多工况点气动反命题的变域变分理论,可以保证叶栅在相当广阔的变工况范围内都能保持优良的运行特性。本理论的突出优点是可较直捷地推广到全三维流动和有旋流动中去,因而具有广阔的发展与应用前景。
A variational formulation of the entitled problem based on anartificial flow-oscillationconcept is presented,enabling cascades to be designedwith favorable performance in a widerange of off-design conditions. The theory can bereadily extended to 3-D and rotational flows.
