锯齿型径向迷宫密封的实验研究

Experimental investigation of crenellated radial labyrinch seals.

采用轴对称多齿迷宫密封模型，实验研究了锯齿型径向迷宫密封的密封性能。结果表明，密封性能并非随着齿插入长度的增加而单调增加，而是存在一个最佳的齿插入长度。

The seal performance of crenellated radial labyrinch seals was studied by using an axial symmetry crenellated labyrinch seal model.The result shows that the seal performance did not monotonely become better with the increase of the length of the inserted saw teeth,whereas there was an optimum length of the inserted saw teeth.
