环形间隙 meaning in Chinese

annular clearance
annular gap
annular space
annulus
circular clearance

With this axial symmetric quasi - 3d model , the gas - flow field in such a wedge - shape air - gap is studied , the phenomena about taylor vortex in such a narrow wedge - shape air - gap is illuminated and the so caused gas - flow in axial direction is explained
采用准三维轴对称的计算模型，对楔形气隙的流场进行了研究，验证了高速旋转情况下，环形间隙流场中充满taylor涡流的现象及相关规律。
