摘要
从“流型”的角度，对比飞行器空气动力学和叶轮机械气体动力学的发展历程，认为叶轮机械内的流动仍在追求定常附体流型，由于其流动及结构特性，使得“有害”分离问题难以避免。本文提出应探索将外流领域内的定常脱体涡流型或下一代非定常脱体涡流型引入到叶轮机械的可能性与技术途径。。本文并综述了上述探索性研究的有关背景和现状，以及所设想的基本途径和影响因素。
As viewed from flow-types,the developing process of aircraft aerodynsmics is compared with that of turbomachine gasdynamics.For the branch of turbomachine′s gasdynamics,it is found that the steady body-fitted flow-type is still the searching object.However,the entire body-fitted flow-type is impossible.It means that the unexpected separations in turbomachinery can not be eliminated.And our comparison has shown that,as for the development of flow-types,the branch of turbomachine′s gasdynamics lags considerably behind the branch of aircraft aerodynamicsSome of the suggestions,with regard to the possible ways of introducing new ideas of flow-types from aircraft aerodynamics into turbomachine gasdynamics,are presented in this paper.
