摘要
求解非定常Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，数值预测了瞬态高压气体通过单空腔迷宫通道的流动，给出了反映流动基本特征的速度矢量图。结果表明，流动结构表现为强冲击、强旋涡和强剪切及瞬态演化的特点，分析了迷宫结构对减小瞬态高压气流泄漏的作用机制。
The unsteady Navier-Stokes equations are solved numerically to predict the flow of transient high pressure gas through single-cavity labyrinth channel.The velocity vectors plots presented show the basic features of the flow which is characterized by intense impact, intense vortex. intense shear and transient evolution. The seal mechanism of labyrinth for transient high pressure gas is also analysed in the paper.
